Dry active electrodes (AE), i.e., the combination of dry electrodes with in situ amplification, are increasingly used for biopotential measurements in emerging healthcare and lifestyle applications [1]. Compared to gel-based wet electrodes, dry electrodes enable fast set-up time, greater user comfort, and long-term monitoring. AE amplifiers ensure local amplification providing improved robustness to noise interference and cable motion artifacts. However, current AEs have analog outputs… CONTINUE READING
