Neural chips keep shrinking, but powering these chips still represents a challenge, especially for applications in the medical domain, such as neural prosthetics. A step towards the direction of reducing this issue has been recently taken by Brian Otis, professor of electrical engineering at the University of Washington. Otis, the lead researcher on NeuralWISP, has designed a microprocessor powered by a commercial radio-frequency reader that doubles as a data-collection device. The circuitry converts usable power from the reader to a voltage that can be used to power the “neural” chip. More information is available here.
