Nanowerk August 9, 2022 Skin-integrated electronics that directly interact with machines are transforming our ways of life toward the emerging trend of the metaverse. Researcher at UCLA have developed a stretchable, inexpensive, and waterproof magnetoelastic sensor array as a secondary skin for self-powered human–machine interaction. The sensor array has the giant magnetomechanical coupling layer made up of nanomagnets and a porous silicone rubber matrix, and the magnetic induction layer, which are coils patterned by liquid metal. With programmable functionalities the sensor array can supply different commands by producing bespoke electric signals from human finger touch with an optimal signal-to-noise ratio […]
