従来は、人工筋肉に使われるアクチュエータは単一で、さまざまな種類の人工筋肉材料を動作原理に使用してきました。 Traditionally, there is a single actuator used for artificial muscles, and various types of artificial muscle materials have been used as operating principles.
そのために、次のような問題点があった。
(イ)単一のアクチュエータだけを用いていたので、どんな優れた人工筋肉材料を使ったとしても、人間の筋肉構造は赤筋と白筋のように二種類であるために、それと同じような動作をさせるには難しかった。
本発明は、これらの問題点を解決するためになされたものである。Therefore, there are the following problems.
(B) Since only a single actuator was used, no matter what superior artificial muscle material was used, there are two types of human muscular structures, red and white, so it is similar to that It was difficult to get it to work.
The present invention has been made to solve these problems.
人工筋肉を二層構造にし、一層目に普段用として膨張・収縮の容易なポリマゲル等の材料を使用したアクチュエータを設け、二層目に緊急用として発生応力と動作速度に優れた電歪ポリマ等の材料を使用したアクチュエータを設けることにより、普段のときに使うものと緊急のときに使うものとを分けることで、人間の筋肉構造の赤筋と白筋の動作に近い使い方が可能になる。以上を特徴とする二層構造の人工筋肉。 The artificial muscle has a two-layer structure, and the first layer is equipped with an actuator that uses polymer gel and other materials that can be easily expanded and contracted for everyday use, and the second layer is an electrostrictive polymer with excellent stress and operating speed for emergency use. By providing an actuator using this material, it is possible to use the human muscle structure close to the movement of the red and white muscles by separating the ones used in normal times and those used in emergency situations. A two-layered artificial muscle characterized by the above.
前記二つのアクチュエータを併用し、用途に合った出力割合を制御することによって、多様性に優れた筋肉動作ができる。以上を特徴とする二層構造の人工筋肉。 By using the two actuators in combination and controlling the output ratio according to the application, it is possible to perform a variety of muscle movements. A two-layered artificial muscle characterized by the above.
人工筋肉を二層構造にして、一層目に膨張・収縮の容易なポリマゲル等の材料を使用したアクチュエータを設け、二層目に発生応力と動作速度に優れた電歪ポリマ等の材料を使用したアクチュエータを設けることにより、普段のときと緊急のときに使うものとで分けることで、人間の筋肉構造の赤筋と白筋の動作に近い使い方が可能となる。またそれらを併用させることにより、用途に合った出力割合を制御すれば、多様性に優れた人間の筋肉動作により近づけることができる。また、電歪ポリマ等の材料を使用した二層目のアクチュエータは、動作速度と発生応力並びに収縮の強さもあるので良い硬化性が得られるなどのことから、外からの衝撃を防御するのが容易であるという効果も得られる。 The artificial muscle has a two-layer structure, and the first layer is provided with an actuator that uses a polymer gel or other material that can easily expand and contract, and the second layer uses a material such as an electrostrictive polymer that excels in generated stress and operating speed. By providing an actuator, it is possible to use it close to the movement of the red and white muscles of the human muscular structure by separating them from those used in normal and emergency situations. Moreover, by using them in combination, it is possible to approach human muscle movement with excellent diversity by controlling the output ratio according to the application. Also, the second-layer actuator using materials such as electrostrictive polymer has good sclerosis because it has operating speed, generated stress and strength of shrinkage, so it can protect against impact from outside. The effect that it is easy is also acquired.

(イ) 二層構造にするために、伸縮に強いゴム等の材質を使用した境界膜(1)と外膜(2)を設ける。
(ロ) 膨張・収縮の容易なポリマゲル等の材料を使用した一層目のアクチュエータ(3)に、電極A(4)を設ける。
(ハ) 発生応力と動作速度に優れた電歪ポリマ等の材料を使用した二層目のアクチュエータ(5)に、電極B(6)を設ける。
(ニ) 電極A(4)と電極B(6)を、制御装置及び電源等に接続する。
(ホ) 骨部(7)と人工筋肉本体(8)との間に、伸縮に強い接続ジョイント(9)を設けて固定する。
