Photothermal actuators are widely applied in robots, smart devices, and bionic systems. However, asymmetric thermal expansion, the most common mechanism for preparing photothermal actuators, has not been utilized in programmable liquid metal photothermal actuators. In this work, Liquid metal/Polyimide/Polytetrafluoroethylene (LM/PI/PTFE) programmable photothermal actuators based on asymmetric thermal...
Liquid Metal Photothermal Actuators
Inspired by tendrils, in article number 2310380, Xingyou Tian, Xian Zhang, and co‐workers prepare programmable liquid metal/polyimide/polytetrafluoroethylene photothermal actuators based on asymmetric thermal expansion. With finite element analysis and programmable morphology, soft robots with various functions are designed. The work provides a new strategy for...
