Wireless Bioelectronic Technologies, Therapies, and Diagnostics

Bioelectronics provide unparalleled capabilities in sensing and modulating the rich tapestry of signals regulating living systems. Their ability to target physiological signals on and within the human body, however, has so far been limited to a few anatomical regions and/or short durations of time, primarily limited by the physical inaccessibility of the underlying tissue. A key challenge over the next decade will be to expand this spatiotemporal access by orders of magnitude in order to leverage advances in microelectronics and nanotechnology for new therapies and diagnostics that address currently intractable disorders. In this talk, I will describe our work on wireless technologies for bioelectronics and their applications in medicine. I will present approaches to wirelessly power and extract data from deeply implanted microdevices that are not accessible by conventional means, and discuss how these technologies can enable new therapies, including a targeted form of cancer treatment based on the wireless delivery of light. I will also highlight an approach to efficiently and securely interconnect wireless networks of wearable sensors using metamaterial textiles, inspired by the way that light propagates on metallic surfaces.
