Magneto-mechanical micro-antenna for implantable devices

Implantable/wearable devices promise to revolutionize health care by permitting early diagnosis of diseases. To be safely implanted inside the human body, biosensors must be miniaturized down to sub-millimeter dimensions and rely on wireless power and communication. These characteristics make powering these sensors extremely challenging. Strategies for power transmission using electromagnetic and ultrasound waves would need to operate at very high frequencies, drastically reducing the penetration of the waves inside living tissue and, thus, the powering efficiency. Living tissues are, however, transparent to magnetic fields. Mechanical antennas integrating magnetic materials are a promising alternative for efficient power transmission to small devices. This project consists in developing a novel magnetically-driven mechanical micro-antenna to be used on sub-millimeter devices.

This project is a collaboration between Dr. Tomás Manzaneque (EI) and Dr. Filipe Cardoso (EI).
