This paper presents a non-contact electrocardiogram (ECG) measurement platform that compensates for motion-induced impedance changes via interdigitated electrode channels in concert with software reconstruction algorithms. Specifically, the impedance of the non-contact electrode is non-invasively acquired in real-time by exploiting a custom electrode designed with two independent channels featuring independent transfer functions that are used to reconstruct motion-compensated ECG waveforms. The developed platform is validated on human subjects, illustrating up to a 76.3% improvement over conventional approaches, paving the path towards comfortable, convenient, and robust non-contact electrophysiological sensing.
