Dr. Sayrafian talks about the next big thing in our lives, wearable and implantable sensors, used mainly in mobile health. He explains how we can power them with energy from microharvesters that exploit the natural movement of our body, producing energy proportional to their size, and reveals a user-centric and quite challenging vision for health future: patients and seniors living better at home and away from the hospital, yet better monitored and cared of. Thanks to modern health services that follow them everywhere. Interviewed by Yannis Rizopoulos for Tech Talks Central.
