Piezoelectric‐Driven Self‐Sensing Leaf‐Mimic Actuator Enabled by Integration of a Self‐Healing Dielectric Elastomer and a Piezoelectric Composite

Soft robots and devices exploit highly deformable materials that are capable of changes in shape to allow conformable physical contact for controlled manipulation. While soft resilient mechanical impact, they susceptible damage, such as tears punctures. The development self-healing actuators continues attract increasing interest, particular, with respect integrating polymers create bioinspired devices. Herein, a novel piezoelectric-driven leaf-motion mimic actuator is designed by combining thermoplastic methyl thioglycolate–modified styrene–butadiene–styrene (MGSBS) elastomer piezoelectric macrofiber composite (MFC) self-sensing applications. This article the first demonstration actuator-sensor system, which driven can leaf motion. combines built-in dynamic sensing room-temperature capabilities restore macroscale cutting damage an intrinsically high bandwidth up 10 kHz. feasibility potential new use complex autonomous systems demonstrated. These results help address emerging influence challenges sensing, actuation, resistance robotics.
