Radio frequency integrated circuits for biomedical applications

Wireless communications devices now allow us to get information anywhere anytime.  This technology, often used in consumer applications, can improve our lives by keeping us in touch with others.  In the future, wireless devices can also be used to improve the quality of our health care.  Medical sensors can be embedded in the body, ingested, or simply placed on the surface of the skin from where they relay vital information over a wireless link.  Researching this technology will provide the advantage of medical care with less invasive, lower risk procedures.  Since it is often impractical for an embedded or ingestible sensor to operate from a conventional battery power source, these applications will require innovative low power radios that are self-powered.  New biomedical applications are going to pose challenges both at the circuit and the system level for the radio design.  New radio architectures will need to be developed to handle progressively challenging requirements.  As well, innovation at the circuit level will be needed to implement architectures with extremely low size, and power requirements.  Thus, a broad understanding of issues at all levels of radio design, from device to system architecture will need to be applied.  It will be the goal of this research project to first fully understand all these issues at the circuit and system levels, and then use that understanding to realize new approaches to allow wireless sensors to be used to improve the quality of health care for all Canadians.
