Human-Machine Interfaces Work Underwater, Generate Their Own Power
American Institute of Physics (AIP)In Applied Physics Reviews, scientists at UCLA describe their development of a type of wearable human-machine interface device that is stretchable, inexpensive, and waterproof. The device is based on a soft magnetoelastic sensor array that converts mechanical pressure from the press of a finger into an electrical signal. The device involves two main components: a layer that translates mechanical movement to a magnetic response and a magnetic induction layer consisting of patterned liquid metal coils.
