Electrical engineers at the University of Washington have developed an implantable neural sensing chip that needs less power, drawing power from a RFID reader radio source up to a meter away.

The NeuralWISP is a collection of smaller, more low-power components, such as a specialized signal amplifier, on a circuit board just over two centimeters long. A future version will integrate all components onto a single chip that’s one millimeter by two millimeters in size.
