Abstract

This paper presents the implementation of a miniaturized wireless blood pressure sensor interface. The system uses capacitive coupling in order to transmit the data, as well as wireless inductive powering. Designed for a bit length of 6.4 μs, the average power consumption of the device has been measured to be 20.5 μW and 2.85 mW in air and phantom material, respectively. The miniaturized sensor interface circuit consists of two plates with a diameter of 2.5 cm, which are connected by means of a thin wire; the device's maximum thickness is 5 mm.
