Design of a Miniaturized Wireless Blood Pressure Sensing Interface using Capacitive Coupling
Résumé
This paper presents the implementation of an implantable wireless blood pressure sensor interface. The system uses capacitive coupling in order to transmit the data, as well as a wireless inductive powering. Designed for a bit length of 6.4 s, the average power consumption of the implant has been measured to be 20.5 W and 2.85 mW in air and phantom material respectively. The diameter of the implant is 2.5 cm, and its thickness is 5mm.
