Human-machine interfaces work underwater, generate their own power

16

Scientists describe the 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.
