Abstract

FLEXcon has developed novel electrocardiogram electrodes that use a dry interface that does not dehydrate over time, in contrast to the current industry standard Ag/AgCl hydrogel electrodes which require dehydration barriers in packaging and dry out over a few days. The optimized carbon to pressure sensitive adhesive concentration for the minimum material impedance is 10% carbon to 90% PSA. Optimal activation parameters are 200 V, 100 mA, and a 100 ms discharge time. Signal processing of ECG waveforms conclude that the 10% carbon concentration electrodes, at the largest size given by FLEXcon for testing, are able to substitute the hydrogel Ag/AgCl electrodes in a clinical setting.
