Abstract :
As the power is at a premium in a wireless powered microvalve, it necessitated the design and development of a contactless powering system specific to implant functionality. We present a custom design and development of the biotelemetry system for the implanted microvalve, using FEM modelling and experimental validation in the presence of numerical and physical human body phantoms, respectively. A comprehensive 3-dimensional FEM modelling and physical validation of an inductively coupled link comprising a 6×6×0.5 mm conformal spiral implanted antenna and a 8×5×0.2 cm spiral transmitter antenna is demonstrated. In addition to the investigation of the quality factor and inductance of individual coils, an analysis of the received relative signal response of the implanted antenna is presented.
