New sensor could lead to artificial skin with superhuman perception

Researchers from the University of Connecticut and University of Toronto developed a sensor that mimics the skin's sensing abilities and can detect magnetic fields and sound waves. The sensor consists of a silicone tube wrapped in copper wire and filled with iron oxide nanoparticles. When the nanoparticles move, they generate an electric current, which is detected by the copper wire. This allows the sensor to distinguish between different types of signals, such as pressure, sound waves, and magnetic fields. The team envisions applications for burn victims and as safety systems for workers exposed to high magnetic fields.
