  • Silicone-based highly stretchable multifunctional fiber pumps
    Ryo Kanno; Keita Shimizu; Kazuya Murakami; Yuya Shibahara; Naoki Ogawa; Hideko Akai; Jun Shintake
    Last, Scientific Reports, Springer Science and Business Media LLC, 14, 1, 4618, 26 Feb. 2024, Peer-reviwed, Abstract

    Recent advancements on electrohydrodynamic (EHD) soft pumps demonstrate their applicability to various fluid-driven systems such as soft robots, wearable devices, and stretchable electronics. In particular, fiber type EHD pumps reported more recently is a promising pumping element thanks to their versatile fibrous structure. Yet existing EHD fiber pumps are less stretchable and require sophisticated, complex fabrication equipment, implying opportunity for technology advancement. This paper presents a simplified method to create highly stretchable multifunctional fiber EHD pumps. The method employs highly compliant silicone elastomers for the fiber structure that is formed by simple dipping fabrication process. The fabricated pumps (length of 100 mm, inner diameter 4 mm, and mass 5.3 g) exhibit a high stretchability (up to 40% strain) and flow rate and pressure of 167.4 ± 7.6 mL/min (31.6 mL/min/g) and 4.1 ± 0.6 kPa (0.8 kPa/g), respectively. These performances are comparable or even higher than those of previously reported EHD pumps including fiber types. The output performance of the fabricated pumps remain constant for repeated strain cycles (0–25%, up to 2000 cycles) and bending angle up to 180° (corresponding to curvature of 0–30/m). Moreover, the pumps demonstrate unprecedented functionality as a sensor to distinguish the type of fluid inside the tube and to detect strains by reading the capacitance between the electrodes. The characterization result reveals the sensing ability of the pumps as high repeatability up to 30% strain with negligible hysteresis, which is consistent for 5000 cycles.

    Advanced Science, Wiley, 15 Jan. 2024, Peer-reviwed, Abstract

    In minimally invasive surgery, such as cardiac ablation, magnetically steered catheters made of variable‐stiffness materials can enable higher dexterity and higher force application to human tissue. However, the long transition time between soft and rigid states leads to a significant increase in procedure duration. Here, a fast‐response, multisegmented catheter is described for minimally invasive surgery made of variable‐stiffness thread (FRVST) that encapsulates a helical cooling channel. The rapid stiffness change in the FRVST, composed of a nontoxic shape memory polymer, is achieved by an active cooling system that pumps water through the helical channel. The FRVST displays a 66 times stiffness change and a 26 times transition enhancement compare with the noncooled version. The catheter allows for selective bending of each segment up to 127° in air and up to 76° in water under an 80 mT external magnetic field. The inner working channel can be used for cooling an ablation tip during a procedure and for information exchange via the deployment of wires or surgical tools.

  • Robot locomotion by fluid–fluid interaction
    Hiroto Kitamori; Shunsuke Kudoh; Jun Shintake
    Last, Scientific Reports, Springer Science and Business Media LLC, 13, 1, 11 Dec. 2023, Peer-reviwed, Abstract

    This paper describes a locomotion strategy for robots based on the interaction between two fluids, through the development of an untethered mobile robot. The fundamental principle of robot locomotion is to exploit the active deformations of ferrofluid caused by internal magnetic fields, which generate reaction forces to the surrounding fluid (in this study, water). The developed robot is equipped with two permanent magnets (PMs), two electromagnets (EMs), two clusters of ferrofluid, and a control unit with batteries. It has a length, width, and mass of 107 mm, 94 mm, and 127 g, respectively. In the robot, PMs are used to hold clusters of ferrofluid. The activation of EMs by the controller achieves forward and rotational movements of the robot. Experimental results show the forward speed and rotational speed in water to be 2.7 mm/s (at a driving frequency of 9 Hz) and 1.2°/s (at a driving frequency of 7 Hz), respectively. The measured thrust force of the robot is 2 mN, further supporting the concept of robot locomotion by fluid–fluid interaction.

    Last, Advanced Intelligent Systems, Wiley, 5, 9, 02 Jun. 2023, Peer-reviwed, Biodegradable materials decompose and return to nature. This functionality can be applied to derive robotic systems that are environmentally friendly. This study presents a fully biodegradable soft actuator, which is one of the key elements in “green” soft robotics. The working of the actuator is based on an electrohydraulic principle, which is similar to that of hydraulically amplified self‐healing electrostatic actuators. The actuator developed in this study consists of a dielectric film made of polylactic acid (PLA) and polybutylene adipate‐co‐terephthalate (PBAT), with soybean oil as the dielectric liquid and electrodes made from a mixture of gelatin, glycerol, and sodium chloride (NaCl). The synthesized biodegradable electrode material exhibits a Young's modulus of 0.06 MPa and resistivity of 258 Ω·m when the mass fraction of NaCl relative to the amount of gelatin and glycerol is 10 wt%. The softness and resistivity of the electrode material results in actuation strain values of 3.2% (at 1 kV, corresponding to 1.2 kV mm−1) and 18.6% (at 10 kV, corresponding to 9.6 kV mm−1) for the linear‐type and circular‐type actuators, respectively. These values obtained for the biodegradable electrohydraulic soft actuators are comparable to those of nonbiodegradable actuators of the same type, representing the successful implementation of the concept.

  • Polyvinyl chloride-added dibutyl adipate for high-performance electrohydrodynamic pumps
    Keita Shimizu; Kazuya Murakami; Naoki Ogawa; Hideko Akai; Jun Shintake
    Last, Frontiers in Robotics and AI, Frontiers Media SA, 10, 29 Mar. 2023, Peer-reviwed, Electrohydrodynamic (EHD) pumps are a promising driving source for various fluid-driven systems owing to features such as simple structure and silent operation. The performance of EHD pumps depends on the properties of the working fluid, such as conductivity, viscosity, and permittivity. This implies that the tuning of these parameters in a working fluid can enhance the EHD performance. This study reports a method to modify the properties of a liquid for EHD pumps by mixing an additive. Specifically, dibutyl adipate (DBA) and polyvinyl chloride (PVC) are employed as the working fluid and the additive, respectively. The results show that when the concentration of PVC is 0.2%, the flow rate and pressure at applied voltage of 8 kV take highest value of 7.85 μL/s and 1.63 kPa, respectively. These values correspond to an improvement of 109% and 40% for the flow rate and pressure, respectively, compared to the pure DBA (PVC 0%). When the voltage is 10 kV, the flow rate of 10.95 μL/s and the pressure of 2.07 kPa are observed for DBA with PVC concentration of 0.2%. These values are more than five times higher than those observed for FC40 at the same voltage (2.02 μL/s and 0.32 kPa). The results also suggest that optimal conductivity and viscosity values exist for maximizing the EHD performance of a liquid. This demonstrates the validity of the proposed method for realizing high-performance EHD pumps by using additives in the working fluid.

  • Soft-body dynamics induces energy efficiency in undulatory swimming: A deep learning study
    Guanda Li; Jun Shintake; Mitsuhiro Hayashibe
    Frontiers in Robotics and AI, Frontiers Media SA, 10, 09 Feb. 2023, Peer-reviwed, Recently, soft robotics has gained considerable attention as it promises numerous applications thanks to unique features originating from the physical compliance of the robots. Biomimetic underwater robots are a promising application in soft robotics and are expected to achieve efficient swimming comparable to the real aquatic life in nature. However, the energy efficiency of soft robots of this type has not gained much attention and has been fully investigated previously. This paper presents a comparative study to verify the effect of soft-body dynamics on energy efficiency in underwater locomotion by comparing the swimming of soft and rigid snake robots. These robots have the same motor capacity, mass, and body dimensions while maintaining the same actuation degrees of freedom. Different gait patterns are explored using a controller based on grid search and the deep reinforcement learning controller to cover the large solution space for the actuation space. The quantitative analysis of the energy consumption of these gaits indicates that the soft snake robot consumed less energy to reach the same velocity as the rigid snake robot. When the robots swim at the same average velocity of 0.024 m/s, the required power for the soft-body robot is reduced by 80.4% compared to the rigid counterpart. The present study is expected to contribute to promoting a new research direction to emphasize the energy efficiency advantage of soft-body dynamics in robot design.

  • Modeling and Characterization of Tensegrity Structures Integrating Dielectric Elastomer Actuators
    Shuya Watanabe; Yusuke Ikemoto; Jun Shintake
    Advanced Engineering Materials, Wiley, 25, 8, 18 Jan. 2023, Tensegrity structures, architectures that consist of elastic cables and rigid rods, have attracted attention as a building block of robots because of their compliance, lightweight properties, and mechanical robustness. This article describes a method to create electroactive tensegrity structures that employs a dielectric elastomer actuator (DEA) as the actuation principle. Two different types of DEA‐tensegrities are considered herein: a membrane type and a cable type. In these devices, DEAs are made of an acrylic elastomer (3 m, VHB 4905) and a stretchable conductive film (Adhesives Research, ARcare 90336) used as dielectric and electrode layers, respectively. An analytical model of DEA‐tensegrities is built that guides the fabrication of experimental devices. The fabricated DEA‐tensegrities are characterized by the actuation strain in the height direction. As a result, voltage‐controlled actuation strains of 7.5% and 2.0% are observed at 10 kV for membrane type and cable type DEA‐tensegrity, respectively, while the model prediction captures the actuation characteristics.

  • Peristaltic micropump using polyvinyl chloride gels with micropatterned surface
    Tomoki Motohashi; Naoki Ogawa; Hideko Akai; Jun Shintake
    Last, Scientific Reports, Springer Science and Business Media LLC, 12, 1, 30 Dec. 2022, Peer-reviwed, Abstract

    This paper presents a pump using polyvinyl chloride (PVC) gel. PVC gels are compliant, have a simple structure, and exhibit large deformation at voltages in the range of 100–1000 V, which make them suitable for micropumps. In this study, a PVC gel sheet with a surface pattern that enhances active deformation in the thickness direction was employed for the fabrication of a pump. To this end, the PVC gel sheet was sandwiched between three sets of anode and cathode electrodes, after which voltages were sequentially applied to these electrodes to generate a peristaltic deformation of the gel sheet, thus pushing the liquid and creating a one-directional flow. Various pumps were fabricated using PVC gel sheets with different surface patterns, and the pumps were characterized. The pumps exhibited an outline dimension of 35 mm × 25 mm with a thickness of 4 mm, corresponding to a total volume of 3.5 × 103 mm3. The results revealed that the pump fabricated using a 174-μm-high pyramid-patterned gel sheet generated a flow rate of 224.1 µL/min at an applied voltage of 800 V and a driving frequency of 3 Hz. This observed value is comparable to or better than those of existing pumps based on smart materials.

    Toshiaki Nagai; Jun Shintake
    Last, Polymers, MDPI AG, 14, 21, 4549-4549, 27 Oct. 2022, Peer-reviwed, In this study, an antagonistic actuator using dielectric elastomer actuators (DEAs) is developed to investigate the use of rolled DEAs in underwater robots. The actuator consists of a backbone, an elastic hinge, and two rolled DEAs placed in an antagonistic fashion, allowing for the generation of bidirectional movements of the actuator tip. To prove this concept, an analytical model of the actuator is built. The experimental samples are fabricated based on the specification determined by the model. In the fabricated actuator, each rolled DEA has a diameter of 6 mm and a length of 21 mm. The whole device weighs 1.7 g. In the tested voltage range of 0–1200 V, the actuator exhibits a voltage-controllable angle and torque of up to 2.2° and 11.3 mN∙mm, respectively. The actuator is then implemented into a swimming robot, which shows forward speed of 0.9 mm/s at the applied voltage of 1000 V and the driving frequency of 10 Hz. The results demonstrate the feasibility of using rolled DEAs in underwater robots.

    Lead, Smart Materials and Structures, IOP Publishing, 31, 2, 025028-025028, 19 Jan. 2022, Peer-reviwed, Abstract

    This paper investigates the characteristics of sliding ring materials (SRMs), which are promising elastomeric materials for dielectric elastomer actuators (DEAs). Two different types of SRMs with Young’s modulus of 0.8 MPa and 3.3 MPa, respectively, are prepared, and their material and mechanical properties and electro-mechanical performances at electric fields of up to 30 V µm−1 are characterized. For comparison, the same tests are also performed on several commercially available elastomers: Elastosil 2030, Ecoflex 00-30, CF19-2186, and VHB 4905. The results reveal that SRMs demonstrate negligible Mullins effect and hysteresis, while their dielectric strength (62.4–112.4 V µm−1) and viscoelasticity ($\tan \delta $ 0.07–0.24 at 10 Hz) are comparable or even superior to those of other elastomers. In addition, elongation at break is found to be 163.8%–172.1%. SRMs exhibit excellent electro-mechanical performance; for instance, one of the two types has an actuation force 293.2 mN at 24.9 V µm−1 and a strain of 5.2% at 22.3 V µm−1. These values are the largest or larger than most of the tested elastomers. The high performance of SRMs results from their dielectric constant, which ranges from 10.3 to 13.4, leading to an electro-mechanical sensitivity of up to 15.3 MPa−1. These results illustrate SRMs as attractive material options for DEAs.

  • Dielectric Elastomer Fiber Actuators with Aqueous Electrode
    Keita Shimizu; Toshiaki Nagai; Jun Shintake
    Last, Polymers, MDPI AG, 13, 24, 4310-4310, 09 Dec. 2021, Peer-reviwed, Dielectric elastomer actuators (DEAs) are one of the promising actuation technologies for soft robotics. This study proposes a fiber-shaped DEA, namely dielectric elastomer fiber actuators (DEFAs). The actuator consisted of a silicone tube filled with the aqueous electrode (sodium chloride solution). Furthermore, it could generate linear and bending actuation in a water environment, which acts as the ground side electrode. Linear-type DEFA and bending-type DEFA were fabricated and characterized to prove the concept. A mixture of Ecoflex 00–30 (Smooth-On) and Sylgard 184 (Dow Corning) was employed in these actuators for the tube part, which was 75.0-mm long with outer and inner diameters of 6.0 mm and 5.0 mm, respectively. An analytical model was constructed to design and predict the behavior of the devices. In the experiments, the linear-type DEFA exhibited an actuation strain and force of 1.3% and 42.4 mN, respectively, at 10 kV (~20 V/µm) with a response time of 0.2 s. The bending-type DEFA exhibited an actuation angle of 8.1° at 10 kV (~20 V/µm). Subsequently, a jellyfish-type robot was developed and tested, which showed the swimming speed of 3.1 mm/s at 10 kV and the driving frequency of 4 Hz. The results obtained in this study show the successful implementation of the actuator concept and demonstrate its applicability for soft robotics.

  • Monolithic Stacked Dielectric Elastomer Actuators
    Jun Shintake; Daiki Ichige; Ryo Kanno; Toshiaki Nagai; Keita Shimizu
    Lead, Frontiers in Robotics and AI, Frontiers Media SA, 8, 25 Nov. 2021, Peer-reviwed, Dielectric elastomer actuators (DEAs) are a promising actuator technology for soft robotics. As a configuration of this technology, stacked DEAs afford a muscle-like contraction that is useful to build soft robotic systems. In stacked DEAs, dielectric and electrode layers are alternately stacked. Thus, often a dedicated setup with complicated processes or sometimes laborious manual stacking of the layers is required to fabricate stacked actuators. In this study, we propose a method to monolithically fabricate stacked DEAs without alternately stacking the dielectric and electrode layers. In this method, the actuators are fabricated mainly through two steps: 1) molding of an elastomeric matrix containing free-form microfluidic channels and 2) injection of a liquid conductive material that acts as an electrode. The feasibility of our method is investigated via the fabrication and characterization of simple monolithic DEAs with multiple electrodes (2, 4, and 10). The fabricated actuators are characterized in terms of actuation stroke, output force, and frequency response. In the actuators, polydimethylsiloxane (PDMS) and eutectic gallium–indium (EGaIn) are used for the elastomeric matrix and electrode material, respectively. Microfluidic channels are realized by dissolving a three-dimensional printed part suspended in the elastomeric structure. The experimental results show the successful implementation of the proposed method and the good agreement between the measured data and theoretical predication, validating the feasibility of the proposed method.

  • Characterization of Sustainable Robotic Materials and Finite Element Analysis of Soft Actuators Under Biodegradation
    Toshiaki Nagai; Ashitaka Kurita; Jun Shintake
    Last, Frontiers in Robotics and AI, Frontiers Media SA, 8, 24 Nov. 2021, Peer-reviwed, Biodegradability is an important property for soft robots that makes them environmentally friendly. Many biodegradable materials have natural origins, and creating robots using these materials ensures sustainability. Hence, researchers have fabricated biodegradable soft actuators of various materials. During microbial degradation, the mechanical properties of biodegradable materials change; these cause changes in the behaviors of the actuators depending on the progression of degradation, where the outputs do not always remain the same against identical inputs. Therefore, to achieve appropriate operation with biodegradable soft actuators and robots, it is necessary to reflect the changes in the material properties in their design and control. However, there is a lack of insight on how biodegradable actuators change their actuation characteristics and how to identify them. In this study, we build and validate a framework that clarifies changes in the mechanical properties of biodegradable materials; further, it allows prediction of the actuation characteristics of degraded soft actuators through simulations incorporating the properties of the materials as functions of the degradation rates. As a biodegradable material, we use a mixture of gelatin and glycerol, which is fabricated in the form of a pneumatic soft actuator. The experimental results show that the actuation performance of the physical actuator reduces with the progression of biodegradation. The experimental data and simulations are in good agreement (R2 value up to 0.997), thus illustrating the applicability of our framework for designing and controlling biodegradable soft actuators and robots.

    Underwater robots are useful for exploring valuable resources and marine life. Traditional underwater robots use screw propellers, which may be harmful to marine life. In contrast, robots that incorporate the swimming principles, morphologies, and softness of aquatic animals are expected to be more adaptable to the surrounding environment. Rajiform is one of the swimming forms observed in nature, which swims by generating the traveling waves on flat large pectoral fins. From an anatomical point of view, Rajiform fins consist of cartilage structures encapsulated in soft tissue, thereby realizing anisotropic stiffness. We hypothesized that such anisotropy is responsible for the generation of traveling waves that enable a highly efficient swimming. We validate our hypothesis through the development of a stingray robot made of silicone-based cartilages and soft tissue. For comparison, we fabricate a robot without cartilages, as well as the one combining soft tissue and cartilage materials. The fabricated robots are tested to clarify their stiffness and swimming performance. The results show that inclusion of cartilage structure in the robot fins increases the swimming efficiency. It is suggested that arrangement and distribution of soft and hard areas inside the body structure is a key factor to realize high-performance soft underwater robots.

  • Rollable Multisegment Dielectric Elastomer Minimum Energy Structures for a Deployable Microsatellite Gripper
    Oluwaseun A. Araromi; Irina Gavrilovich; Jun Shintake; Samuel Rosset; Muriel Richard; Volker Gass; Herbert R. Shea
    IEEE-ASME TRANSACTIONS ON MECHATRONICS, IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 20, 1, 438-446, Feb. 2015, Peer-reviwed, Debris in space presents an ever-increasing problem for spacecraft in Earth orbit. As a step in the mitigation of this issue, the CleanSpace One (CSO) microsatellite has been proposed. Its mission is to perform active debris removal of a decommissioned nanosatellite (the CubeSat SwissCube). An important aspect of this project is the development of the gripper system that will entrap the capture target. We present the development of rollable dielectric elastomer minimum energy structures (DEMES) as the main component of CSO's deployable gripper. DEMES consist of a prestretched dielectric elastomer actuator membrane bonded to a flexible frame. The actuator finds equilibrium in bending when the prestretch is released and the bending angle can be changed by the application of a voltage bias. The inherent flexibility and lightweight nature of the DEMES enables the gripper to be stored in a rolled-up state prior to deployment. We fabricated proof-of-concept actuators of three different geometries using a robust and repeatable fabrication methodology. The resulting actuators were mechanically resilient to external deformation, and display conformability to objects of varying shapes and sizes. Actuator mass is less than 0.65 g and all the actuators presented survived the rolling-up and subsequent deployment process. Our devices demonstrate a maximum change of bending angle of more than 60 degrees and a maximum gripping (reaction) force of 2.2 mN for a single actuator.

  • DEA for soft robotics: 1-gram actuator picks up a 60-gram egg
    Jun Shintake; Samuel Rosset; Bryan Schubert; Stefano Mintchev; Dario Floreano; Herbert Shea
    Lead, ELECTROACTIVE POLYMER ACTUATORS AND DEVICES (EAPAD) 2015, SPIE-INT SOC OPTICAL ENGINEERING, 9430, 94301S, 2015, Peer-reviwed, We introduce a soft actuator for grippers using DEA capable of bending actuation. The actuator is also able to generate the electro-adhesion by the fringe field formed at the edges of the electrodes. The adhesion improves the holding force and ensures the conformation of the structure to the object. After the characterization of the actuator, we develop a 2-finger soft gripper capable of holding various objects. The gripper has a mass of around 1 g, and consists of a few cm long actuation parts, realizing simple open-close movement. The compliance of the gripper leads to conformation of the structure against the object surface, which is proven by successful handling of objects with different geometries such as a toothbrush, a flat paper, and a ping pong ball. The effect of the electro-adhesion is visible when the paper is held with its flat shape meaning that an adhesion force against gravity exists. Also, by the fact that the conformed structure increases the contact area, the holding force is improved while avoiding damaging the object, which is highlighted by the ability to hold a raw egg weighing around 60 g. This soft gripper, combining both actuation and electro-adhesion, illustrates the potential use of DEA for soft robotics.

Most of the fish type robots developed up to now have complicated mechanisms with complicated motion control. It results in that the structure and the movement of robots are different from those of fishes. The purpose of our work is to develop creaturelike flexible underwater robots by using piezoelectric fiber composite. Compared with conventional artificial muscular underwater robots, powerful underwater robots with a very simple structure can be composed by the piezoelectric fiber composite. This paper describes the development of a flexible underwater robot with pectoral fin propulsion like ray and mode shape propulsion of structural vibration, which can generate various movements.

  • 繊維状ソフトポンプの研究開発:基礎特性の把握
    新竹 純
    日本学術振興会, 科学研究費助成事業 若手研究, 電気通信大学, 若手研究, 本研究は、内部的に実装できる繊維状ソフトポンプの製造方法の確立、ポンプの基礎的な性能特性の明確化、および実機の開発を通したソフトロボティクスへの有効性の検証を行うことを目的としている。本研究で提案する繊維状ソフトポンプは、シリコーンチューブと柔らかい電極から構成される。 当該年度では繊維状ポンプの製造方法の確立に主として取り組んだ。まず、ポンプの母体となるシリコーンチューブの材料および製作工程について試作を通した検討を行い、十分な柔らかさを持つ任意の直径のチューブの作製を可能とする方法を確立した。この方法では、型を用いるモールディングによってチューブを作製する。2種のシリコーンを特定の比率で混合したものを材料とし、型に流し込んで硬化するだけでチューブの作製が完了する。チューブと柔らかい電極の接着も確認でき、それによって基本的なポンプの製造方法を確立することができた。 実験用のポンプを製作する前段階として、液体のシーリングや絶縁耐性の確認を行った。その過程で、当該年度に製作したチューブそのものが、静電アクチュエータとして機能することを見出した。これは、本研究における副次的な成果である。また、繊維状ポンプを特性解析するための、圧力・流用センサーと治具からなるテストベンチの製作を行い、単純なポンプをサンプルとした簡易実験によって測定が正確に行えることを確認した。他方、これまでの知見に基づいて、海外の研究者との共同研究も行った。, 21K14126

  • グリーンロボティクス:生分解性ソフトロボット要素の研究開発
    新竹 純
    日本学術振興会, 科学研究費助成事業 新学術領域研究(研究領域提案型), 電気通信大学, 新学術領域研究(研究領域提案型), 本研究では、機械的な特性と電気的な特性が両立した生分解性材料と、それを適用したアクチュエータやセンサといった要素を開発することを目的としている。材料の電気的な特性の目標値としては、絶縁体の場合は1×10 Ω・m以上、導体の場合は1×10 Ω・m以下としている。機械的な特性の目標値については、ヤング率0.1-2 MPa程度で伸縮性が100%程度の伸び歪みとしている。当該年度では、主材としてゼラチンに着目し、グリセロールや塩化ナトリウム、セルロースを添加剤として、それらの多寡が結果としてできる材料の特性にどのように影響するのかを、実験を通して明らかにした。その結果、電気的特性と機械的特性を満足する材料を得ることができた。 開発した材料を電気的に駆動するソフトアクチュエータに適用し、生分解デバイスとして動作可能かどうかを検証した。具体的には、液体を内包した絶縁性フィルム上に、開発した材料を電極として塗布した静電流体アクチュエータを構成した。液体には植物油、絶縁性フィルムにはポリ乳酸とポリブチレンアジペートテレフタレートの合成樹脂をそれぞれ用いており、これらはいずれも生分解性材料である。実験の結果、アクチュエータは印加電圧に応じた大変形を出力することが確認でき、電気的に駆動される生分解性デバイスとして機能することが分かった。 ゼラチンを主材としたセルロースの添加は海外機関との共同研究という形でも行っており、その副次的な効果として、材料の3Dプリントが可能になることを見出した。これは、セルロースによって流動性を調整できることに起因しており、これまで困難であった柔らかいゼラチン材料の精度の高い3Dプリントができるようになった。これは、当該研究の今後の遂行において非常に強力な手段となるものである。 以上の活動に加え、これまでの知見を活かした共同研究を国内外の研究者と行った。, 21H00324

  • テンセグリティロボットを用いた生物の射出運動生成機構の理解
    池本 有助; 新竹 純
    日本学術振興会, 科学研究費助成事業 基盤研究(B), 名城大学, 基盤研究(B), 本研究の目的は,硬い部材を柔らかい部材の張力によって形態を維持するテンセグリティの設計原理を活用したロボットを開発し,ダンゴムシなどの蛇腹状の多関節を有する生物の逃避行動にみられる瞬間的屈曲運動を実現する.そして,数値シミュレーションおよび実ロボットの具現化を行うことである. 今年度では,開発した射影幾何に基づくテンセグリティロボットシミュレータの数値計算を並列化し,計算コストの大幅な削減が可能となった.また,アクリル板を使用した2Dから3Dのテンセグリティオブジェクト開発方法を確立し,ハードウェア開発の大幅な時間短縮が可能となった.これらのハードウェア設計・製作手法は国内特許に出願した. また,引き続き,テンセグリティ構造体の最適化アルゴリズムを双安定力学系に基づき考察した.その結果,数値シミュレーション結果と実機実験との比較を行うことが可能となり,より再現性の高い実験と結果検証が可能となった.この双安定力学特性を用いた構造設計を行い,エビの屈曲状態を維持するテンセグリティ構造体を製作するに至った.本結果は,国際会議でのポスター発表を行った. また,ソフト材料とリジッド材料の成型の設計に関し,剛性の異なるソフト材料を混合させる技術基盤を確立した.特に,ソフト材料とリジッド材料の成型を自由自在かつ短時間で行う方法論を駆使し,様々な複合剛性を有するソフトロボットを開発した.本結果は,国際ジャーナルに掲載された., 19H02118

    新竹 純
    日本学術振興会, 科学研究費助成事業 新学術領域研究(研究領域提案型), 電気通信大学, 新学術領域研究(研究領域提案型), 前年度に構築した、微生物による分解に対する生分解性材料の機械特性の変化をパラメータとして実装した、ソフトアクチュエータのシミュレーション環境の妥当性を検証するために、実機アクチュエータとの比較実験を行った。アクチュエータは空気の入力によって曲げ変形するものであり、実験の前段階として、本研究で用いている生分解性材料であるゼラチンとグリセロールの混合物に適した構造、形状、および製作工程を明らかにした。 シミュレーションとの比較実験では、製作したアクチュエータが0、5、10、15、20、および25%の生分解度を持つような、最適な分解条件を明らかにし、これを適用した。実験の結果、分解度ごとのアクチュエータの曲げ動作の変化の傾向はシミュレーションで予測されたものと同様であることが分かった。また、それぞれの分解度における曲げアクチュエーションの変化量も、高い精度でシミュレートできることが分かった。これは実験値とシミュレーション値の間の決定係数で定量的に判断されたもので、それぞれの分解度で0.997までの高い値が得られた。 以上の結果により、生分解性ソフトアクチュエータがどのように変性し、その出力特性がどう変化するのかという、変性機序を明らかにすることができた。そして、それらの挙動を予測するシミュレーション環境の妥当性が明らかになり、生分解性ソフトアクチュエータの設計法の一つとして確立できたことが示された。今後の研究の展開としては、本研究で得られた材料の解析手段や設計法を、様々な生分解性材料に基づくソフトアクチュエータやセンサに適用していくことが挙げられる。 なお、本研究においてアクチュエータの構造や製作方法を検討する過程で、非生分解性材料に基づく柔らかいデバイスの知見も副次的に得ることができた。, 19H05328

    Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Early-Career Scientists, The University of Electro-Communications, Grant-in-Aid for Early-Career Scientists, Stacked dielectric elastomer actuators are a promising technology for soft robotics, but their shape is limited to a certain range of geometries. Moreover, fabrication is laborious and often requires dedicated facilities. In this study, we proposed a novel method for fabricating stacked dielectric elastomer actuators with a very simple process, the molding method. The characteristics of the actuators fabricated based on the proposed method were clarified by experiments and analytical modeling, and the effectiveness of the method for soft robotics was validated through the development of a soft robot., 19K14942
