A low power and convenient bio-impedance monitor, and its application to respiration monitoring

A low power and convenient bio-impedance monitor, which relies on a proprietary ASIC to achieve low power performance, is shown. It can be used in several bio-impedance applications, especially in continuous and wearable applications thanks to its compact form factor and long battery life time. In this paper, we demonstrate its performance for respiration monitoring. The result is compared with that of the reference system, showing a high correlation factor of 0.91.
