Abstract:
In his famous lecture from 1959, âThere's plenty of room at the bottom,â Richard Feynman presented a wild idea of âswallowable surgeonsâ where tiny surgical robots are put inside a blood vessel, travel into the heart, look around, and send the information back to an external controller. These robots can even perform operations and might be permanently incorporated in the body for continuous monitoring. The idea seems like a science fiction dream. In recent years, however, researchers have made major progress on implantable systems that support most of the swallowable surgeon functionalities. Nevertheless, these devices remain mostly restricted to research, in part due to limited miniaturization and power supply constraints.
In this talk, I will address these limitations and show, both theoretically and experimentally, that higher frequency (GHz-range) RF power transmission leads to dramatic receiver miniaturization. I will describe a prototype implementation in CMOS that realizes the above theoretical results. Once it is feasible to continuously supply power to micro implants safely, this opens up new clinical applications of implantable systems. I will introduce some of these new applications.
