Adaptive All-Fiber Actuator for Human–Environment Interaction

) with electro-visual cooperative perceptivity. Integrated with the actuation-triggered triboelectric self-powered sensing and synchronous thermochromic effect, the TCTR actuator can be differentially programmed to perceive material types and object temperature (with a sensitivity of 99.5%), and visualize writing paths. By optimizing fiber alignment and assembly pattern, TCTR demonstrates utility as filter material, smart mask, and electronic textile, which can sense and visualize air contamination degrees, environmental temperature, and respiratory status, as well as achieve thermal management/alarming. This work proposes materials with mechano-electrical-optical cooperation and inspires a facile strategy for human-environment interactive actuators with multiscenario adaptivity.
