Monitoring of physiological signals is effected. In accordance with one or more embodiments, an apparatus, system and/or method is directed to sensing physiological signals such as ECG signals. A skin-contacting electrode apparatus includes an electrically conductive sheet having a conductive surface configured and arranged to contact a subjects skin, and conductive flexible microfibers extending from the conductive surface and configured and arranged to protrude into skin pores and sense an ECG signal.
