Tiny, wireless, injectable chips use ultrasound to monitor body processes

(Columbia University School of Engineering and Applied Science) Researchers at Columbia Engineering report that they have built what they say is the world's smallest single-chip system, consuming a total volume of less than 0.1 mm3. The system is as small as a dust mite and visible only under a microscope. In order to achieve this, the team used ultrasound to both power and communicate with the device wirelessly.
