A Battery-Free Implantable Neural Sensor
“electrical engineers at the University of Washington have developed an implantable neural sensing chip that needs less power. Other wireless medical devices, such as cochlea or retinal implants, rely on inductive coupling, which means the power source needs to be centimeters away. The new sensor platform, called NeuralWISP, draws power from a radio source up to a meter away.”
