Abstract
Cooperative sensors are CSEM's patented solution for biopotential or bioimpedance imaging wearables. As opposed to the state of the art that individually connects passive or active electrodes in a star arrangement, cooperative sensors are active electrodes connected via a two-wire parallel bus, thus achieving an outstanding level of integration in wearables requiring many electrodes. This paper reports on the latest results obtained in the development of an application-specific integrated circuit (ASIC) for miniature cooperative sensors and its integration in a prototype. The current development status achieved the compliance verification of an ambulatory electrocardiograph with respect to the medical standards (IEC 60601-2-47) and evaluated the approach on one healthy subject.
