Abstract

Abstract: Actuation integrated with functions of sensing, signal transmission, and control is urgently needed in the development of advanced intelligent systems, which further stimulates the requirement of multifunctional actuators. Here we develop a multifunctional actuation film that successfully integrates sensing, reporting, and locomotion functions, endowing them with high intelligence for accommodating dynamic environments, providing self-feedback, and autonomously executing missions. It can swell and shrink in response to various organic vapors, resulting in rapid and continuous mechanical deformation. These deformation signals can be automatically and synchronously converted into visual electrical signals by the actuation film. As a result, our actuation film demonstrates powerful dominance and offers an extraordinary building block for artificial muscles, soft robots, sensors, and generators. Graphical Abstract: A multifunctional actuation film with spontaneous electro-feedback function was successfully developed, which integrated sensing, reporting, and locomotion functions, endowing them with high intelligence for accommodating dynamic environments, providing self-feedback, and autonomously executing missions. ga1 Highlights: An actuation film that mimics the self-feedback function of the mammal hair is fabricated. The actuation film exhibits high vaporesponsive performance including high response speed, sensitivity and stability. The actuation film shows high programmability to achieve versatile and complex motions. The actuation film can efficiently convert vapor fluctuations into electric signals.
