Thermally Active Liquid Crystal Network Gripper Mimicking the Self‐Peeling of Gecko Toe Pads

Thermally Active Liquid Crystal Network Gripper Mimicking the Self‐Peeling of Gecko Toe Pads

Self‐peeling of gecko toes is mimicked by integration of film‐terminated fibrillar adhesives to hybrid nematic liquid crystal network (LCN) cantilevers. A soft gripper is developed based on the gecko‐inspired attachment/detachment mechanism. Performance of the fabricated gripper for transportation o...

description Self‐peeling of gecko toes is mimicked by integration of film‐terminated fibrillar adhesives to hybrid nematic liquid crystal network (LCN) cantilevers. A soft gripper is developed based on the gecko‐inspired attachment/detachment mechanism. Performance of the fabricated gripper for transportation of thin delicate objects is evaluated by the optimum mechanical strength of the LCN and the maximum size of the adhesive patch.
