We develop circuits and systems for implantable and ingestible medical devices to enable next-generation therapies and diagnostics. Our work focuses on miniaturization of these devices, design of efficient and robust wireless power/data links, and end-to-end system design for various biomedical applications, including neural stimulation, in vivo biosensing, imaging, and closed-loop drug delivery.
Ultrasonically Powered Implantable Devices
Ingestible Medical Devices
Sensing and Imaging
We use multiple physical modalities and concepts from throughout the hardware-software stack to design systems that perform imaging and sensing in various application domains.
Millimeter-Wave Imaging and Perception
Remote Embedded Target Imaging
Multiphysics Medical Imaging
Resonant Photoelastic Modulation for Time-of-Flight Imaging
Photoacoustic Airborne Sonar System (PASS) for Underwater Imaging
We build circuits and systems that enable an increase in inter-device connectivity by orders of magnitude. We work on both the front end (wireless control of mm-sized devices in everyday environments) and the back end (mm-wave communication for high-data rate backhaul).
