Implantable sensor systems are used to report data collected within the human body to an external device. One of the major challenges with powering an implantable device is the dimensionality of the powering mechanism. Batteries are limited in capacity and take up significant volume, complicating delivery of the sensor into the body. With a wireless approach, only a certain range of frequencies can be used to ensure sufficient power delivery past the human skin within safe boundaries. For my project, I will be working on the simulation, prototyping, and iteration of a hardware system to wirelessly power, transmit, and receive data from an ingestible oxygen sensor. In addition to integrating the antenna network with the rest of the system, I will be optimizing the design to minimize losses.


Through the SuperUROP program, I am looking to grow as a researcher through an intensive year-long research experience. Through transistor-based circuit courses, I have become interested in the design and applications of microelectronics, and I am excited by the interdisciplinary nature of medical devices. I am motivated by the idea of working on small devices that have the potential for tremendous impact on people’s lives.
