Surface electromyography (sEMG) is used to determine muscle activity by picking up the associated bio-potentials using skin-mounted electrodes. In this paper, we study how the electrode and skin impedance of 3D printed sEMG electrodes can be improved by comparing traces made of either silver ink or carbon black loaded thermoplastic polyurethane (TPU). To this end we developed a method, using the AC-lead off of the Texas Instruments ADS1298 analog front-end, to continuously determine the complex impedance during sEMG measurements. We observe that the application of silver-ink reduces both the electrode impedance and its variation during isometric contractions.
