Abstract:

Smart medical devices will play a significant role in wellness, healthcare and medicine. While consumer electronics have become ubiquitous and inexpensive, medical devices, by contrast, are still primarily found only in hospitals. There is a great potential benefit in using techniques developed in the consumer electronic industry and applying them to healthcare applications. To move in this direction, substantial innovation is required to develop new tools that are fundamentally less invasive and use unconventional techniques to address medical challenges. This research explores new opportunities in the boundary of the increasing performance of electronic systems (made possible by Moore's law) and smart ?electromagnetic? interfaces (including array imagers, sensors, and implantable devices).

On the medical imaging front, pulsed-based dielectric imaging of tissue with a Time-Domain Ultra-Wideband Synthetic Imager (TUSI) is proposed. TUSI is designed to be a low-cost and portable device operating in microwave/mm-wave spectrum suitable for specific diagnostic applications. Novel approaches for extreme wideband amplification plus narrow and accurately controllable pulse generation, the key challenges in attaining image quality, are addressed. The transmitter uses a smart 90GHz antenna network, the Antentronic structure, to obtain improved transmit bandwidth. In the end of the presentation, another project example proposing a new architecture for passive transponders, suitable for implantable devices, sensors or immersion applications, is discussed.
