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...
Considerable scientific and technological effort has been devoted to develop implantable wireless stimulator systems for biomedical applications. The main purpose of such stimulator system is to provide electrical excitation to human body cells to help patient re-gain lost body function or rectify fault body function, in an elegant way that there is no notable cosmetic difference when patients are...
This paper presents design of wirelessly powered coils for implantable micro-system for blood flow sensing, and a technique of optimal resonant load transformation. Basics and calculations are also introduced for the wireless powering structure to achieve optimal power transfer efficiency. Measurement results show that the implemented wirelessly powered coils in the implantable blood flow sensing...
