你不会一个人走？本发明涉及一种凝胶致动器，其可以在没有外部驱动刺激的情况下产生具有蠕虫状运动的自主运动性。自主运动是通过耗散凝胶内部发生的振荡反应的化学能而产生的。尽管凝胶完全由合成聚合物组成，但它显示出自主运动，就好像它是“活的”。通过将其与棘轮机制相结合，凝胶就像一个活套一样反复弯曲和伸展（见图）。
You'll never walk alone? A gel actuator that can generate autonomous motility with a wormlike motion without external driving stimuli is produced. The autonomous motion is produced by dissipating the chemical energy of an oscillating reaction occurring inside the gel. Even though the gel is completely composed of synthetic polymer, it shows an autonomous motion as if it were "alive". By coupling this with a ratchet mechanism, the gel walks by repeatedly bending and stretching itself like a looper (see figure).
