Wireless sensor microsystems for emerging biomedical applications (Invited)

In this paper, two examples of wireless sensor microsystems for medical devices are presented: a wireless blood flow monitoring microsystem which is fully integrated with a prosthetic vascular graft for early failure detection, and a 100-channel wireless neural recording microsystem In the context of such biomedical applications, high-efficiency wireless transceiver circuit techniques for data communication and power transfer as well as low-power sensor interface circuit techniques are introduced and explained.
