Autonomous oil flow generated by self-oscillating polymer gels

Vito Cacucciolo

The previously reported gel and polymer actuators require external inputs, such as batteries, circuits, electronic circuits, etc., compared with autonomous motions produced by the living organisms. To realize the spontaneous motions, here, we propose to in ...
