Inventor: ANO JOSE CARLOS CONCHELL
IPC: A61B5/053
Filed: 2019-05-24
Abstract: The exact measurement of bio-impedance is important for sensing the features of a body. Unfortunately, contact impedances may significantly degrade the accuracy of bio-impedance measurements. For dealing with the issue, a current for implementing 4-wire impedance measurement may be configured to measure currents. A simultaneous equation is established to allow measurements for currents to derive unknown bio-impedance and contact impedances. A result is accurate bio-impedance measurement, which is not negatively affected by large contact impedances. In addition, poor contacts with the undesirably large impedances may be identified.
