Brain Implants No Bigger than Dust Particles On the Way

A new concept of a brain-computer interface has been proposed by engineering researchers at University of California Berkeley, utilizing what they term as 'neural-dust', tiny machines that would be implanted in the brain to help facilitate the collection of neurological data.

The tiny components would be powered by piezoelectric materials, of which produce an electric current when compressed, activated by ultrasound waves generated by a transmitter placed on the scalp. The implanted components would have a simple CMOS sensor that would measure the electrical activity being generated by the neurons around it, and re-transmit that back to the sensors on the scalp.
