The Skin Knows It Has Been Cut
A self-powered magnetoelectric sensor detects touch and damage, then restores its function even while submerged.
Summary
A self-powered magnetoelectric sensor detects touch and damage, then restores its function even while submerged.
National University of Singapore engineers combined a stretchable self-healing elastomer, liquid-metal conductors, a magnet, and a coil into a sensor that produces its own touch and proximity signals through electromagnetic induction. Punctures cause a resistance spike that acts as a damage alarm; reversible molecular bonds then reconnect, with small needle damage recovering electrical performance within seconds. Demonstrations included a gesture-sensing diving glove and an underwater robotic hand. The prototypes are laboratory devices, not deployed safety equipment, and severe cuts still require contact and time to regain full function.
