Microscopic, Remotely Powered Implant to Read, Transmit Brainwaves from Inside Skull
Brain-computer interfaces and other technologies that rely on reading and stimulating the brain require electrodes to obtain and deliver signals, as well as a way to transmit those signals from within the brain. Electric wires have usually served as the method of connectivity, but they create serious challenges, including a potential for infection, safety issues,...
