All-Fiber Volatile Organics-Perceptive Actuators

, and excellent stability of 1500 actuation cycles without fatigue, with synchronous VOC-induced piezoelectric output reflecting actuation conditions. VOC-responsive solvatochromic and piezoelectric sensing, manipulation, and robots were demonstrated as applications. The VOC-triggered soft robot demonstrates stable motion with synchronous piezoelectric output, capable of autonomously perceiving and responding to environmental VOC. This work presents a widely applicable interactive visual-electronic VOC detection strategy for safety, health, and environmental protection, which could also inspire the exploitation of high-performance responsive fiber materials.
