Chinese Academy of Sciences Researchers Develop Biomimetic Adaptive Electronic Skin for Robot Tactile Perception
Overview
A team led by Researcher Wei Dapeng at the Chongqing Institute of the Chinese Academy of Sciences has developed a flexible electronic skin based on a biomimetic adaptive mechanism. Published in Nano Research, the device uses a magnetic conductive network to dynamically adjust sensitivity and signal-to-noise ratio under external stimuli. The sensor operates across a wide pressure range from 1 Pa to 3.5 MPa, achieving high sensitivity and fast response, offering new possibilities for robot intelligence in complex environments.
