From an article at kurzweilai.net:
University of California, Berkeley engineers have designed and built millimeter-scale device wireless, batteryless “neural dust” sensors and implanted them in muscles and peripheral nerves of rats to make in vivoelectrophysiological recordings.
The new technology opens the door to “electroceuticals” — bioelectronic methods to monitor and record wireless electromyogram (EMG) signals from muscle membranes and electroneurogram (ENG) signals from local neuron electrical activity, and to stimulate the immune system, reduce inflammation, and treat disorders such as epilepsy.
The technology could also improve neural control of prosthetics (allowing a paraplegic to control a computer or a robotic arm, for example) by stimulating nerves and muscles directly, instead of requiring implanted wires.
