Abstract
The design of a wireless impedance platform for the vascular system of the human body encounters several hurdles. In order to conduct in vivo experiments, these issues must be addressed early to show proof of concept. This paper presents data from our implant-ready sensor to demonstrate its functions in a pseudo-implanted environment. To construct a self-reporting impedance measuring platform for vascular implants, a wireless power and data system is presented. Notably, the implementation of the Radio Frequency (RF) energy harvesting technique contributes to the powering up of self-reported battery-free vascular implants. The harvested RF power is converted to Direct current (DC) power by employing an optimized L-type matching circuit and a two-stage voltage doubler rectifier circuit. This rectifier topology is adopted for driving the high voltage pulses stimulations of vascular implants, which achieves a high voltage output and 93.6 % peak RF-to-DC conversion efficiency at input power of 27 dBm.
