A Suspended, 3D Morphing Sensory System for Robots to Feel and Protect

Abstract

Artificial sensory systems with synergistic touch and pain perception hold substantial promise for environment interaction and human‐robot communication. However, the realization of biological skin‐like functional integration of sensors with sensitive touch and pain perception still remains a challenge. Here, we propose a concept of suspended electronic skins enabling three‐dimensional deformation‐mechanical contact interactions for achieving synergetic ultra‐sensitive touch and adjustable pain perception. The suspended sensory system can sensitively capture tiny touch stimuli as low as 0.02 Pa and actively perceive pain response with reliable 5200 cycles via 3D deformation and mechanical contact mechanism, respectively. Based on the touch‐pain effect, a visualized feedback demo with miniaturized sensor arrays on artificial fingers is rationally designed to give a pain perception mapping on sharp surfaces. Furthermore, we show the capability of the suspended electronic skin serving as a safe human‐robot communication interface from active and passive view through a feedback control system, demonstrating potential in bionic electronics and intelligent robotics.This article is protected by copyright.
