Abstract

Electrically stable electrodes are required for personal healthcare monitoring systems in order to monitor vital parameters without affecting patient lifestyle. This paper presents the electrical characterization of MEMS-based microneedle electrodes for surface bio-potential recording. Electrical measurements are presented for the impedance and DC offset of the electrodes and typical bio-potential signal (ECG, EMG) recordings are illustrated using the electrodes. These results demonstrate the suitability of the new electrodes for long-term wearable recording applications.
