ポリイミドフィルムを用いた収縮型人工筋肉の紹介

抄録

Pneumatic artificial muscle made of polyimide films will be presented. This artificial muscle is made by welding two 25 μm thick PI films together using a welding technique that is free of pretreatment, additives, and adhesives. The artificial muscle is made entirely of PI, which has high heat resistance, high chemical resistance, and high radiation resistance, and is expected to be used in extreme environments. The artificial muscle generated a force approximately 3,600 times greater than its own weight under natural length displacement constraints.
