Natural soft organisms with sophisticated perception and deformation abilities provide inspiration for developing flexible electronics. However, the development of sensing actuating hybrid systems remains a challenge. Herein, we report bioinspired sensor actuator pixel array (SA-HPA) that enables moisture/temperature mapping, electrothermal display, programmable deformation. The SA-HPA is fabricated by femtosecond laser patterning Cu electrodes/circuits, controllable deposition graphene, selective encapsulation, liquid crystal elastomer integration. versatile can work as temperature moisture recognition, interference between them be overcome encapsulation adjacent pixels. Additionally, SA-HPAs also serve pixels infrared display actuation. As proof-of-concept, robotic system active humidity was demonstrated. We deem may new paradigm
