Dielectric elastomers [10 ], liquid-crystal elastomers [ 19 ], hydrogels [ 11 ], carbon-based materials [ 20] and paper-based materials [ 16] have been used for fabricating actuators driven by humidity [ 20 ], organic vapor [ 21 ], light [ 22 ], electricity [ 14, 17, 18] and multi-stimuli [ 15, 16].
The EHA is a linear actuator comprising a hydraulic cylinder as the actuator, which represents a crucial branch of the pump-controlled system, as illustrated in Fig. 1. The structure is an integrated unit with a motor-pump, valve block, and hydraulic cylinders.
Four-quadrant operating principle The actuator of an EHA is subjected to forces in both the push and pull directions. In addition, the speed direction of the actuator includes both extension and retraction. The vector relationship between speed and force forms a planar coordinate system with four quadrants.
Based on the above-mentioned fascinating characteristics of GP paper-based materials and inspiration from electric fish, a multi-functional actuator made with GP4 paper is elaborately designed, which integrates the functions of actuator and supercapacitor in a single device. The fabrication is summarized as follow.
