Recently, the School of Space Science and Technology at Xidian University has achieved significant advancements in the realm of bionic non-contact sensing. Drawing inspiration from the electric localization abilities of electric eels, the research team has introduced a groundbreaking solid-state non-contact sensing technology. This technology harnesses the principles of electret quasi-static electric field disturbances. By establishing an electric field through pre-polarized electrets, it capitalizes on the alterations in the electric field distribution caused by nearby objects to perceive the surrounding environment.

This innovative sensing method has undergone rigorous validation in various practical scenarios, including proximity warnings, material identification, coating defect detection, and non-contact human-machine interaction. One notable application is gesture recognition, where the technology accurately interprets hand gestures by analyzing the potential differences they generate. Furthermore, closed-loop demonstrations have been successfully conducted in conjunction with a robotic arm control system, showcasing the technology's potential for seamless integration into automated processes.

The research findings have garnered international recognition, with publication in the prestigious journal Advanced Materials, a testament to the significance and impact of this breakthrough in the field of bionic sensing.
