Abstract

In this paper, we present a new bio-impedance monitor for wearable and continuous monitoring$r applications. The system consumes less than 14.4mW when measuring impedance, and 0.9mW when idling.$r Its compact size (4.8cm × 3cm × 2cm) makes it suitable for portable and wearable use. The proposed$r system has an accuracy of 0.5$ and resolution of 0.2$ on both resistance (R) and reactance (X)$r measurements, for impedance ranging between (j0.7)$ to (54+j5)$ with 2.9textless IMG$r [http://ej.iop.org/icons/Entities/varphi.gif] varphi textless5.7. We also report the results of the$r system validation using passive loads as human tissue model, and show our wireless and miniaturized$r bio-impedance monitoring system has comparable performances with a reference system.
