Abstract
Disclosed is a combined skin preparation and monitoring electrode (12). The electrode reduces motion artifacts in recording biopotentials by penetrating a patient's skin prior to acquiring biopotentials. Penetration of the skin reduces skin impedance and the skin's propensity to generate motion artifacts. The electrode has a resilient dome (16) with penetration tines (18) extending from the concave inner surface of the dome. Upon application of a force to the dome, the dome moves from a first position to a second position, forcing the penetration tines into a patient's skin. Upon removal of the force, the dome moves back to its original configuration, withdrawing the penetration tines from the patient's skin.
