Barbed dry microtips arrays are fabricated using simple and low-cost silicon wet etching techniques for ECG recording. Compared with standard wet electrodes, the proposed dry electrodes do not require skin preparation or electrolytic gel during the ECG measurement process. We also discuss parameters affecting skin-electrode impedance, such as the thickness of the conductive layer and the driving frequencies. We successfully demonstrate that the proposed dry electrodes can be used to measure ECG signals.
