From: Measuring electro-adhesion pressure before and after contact
Effect of Waveform and Holding time on the EA pressure measured on a dielectric object using an EA patch with electrode width and gap of 100 µm, and a dielectric thickness of 20 µm. (a) and (b) Adhesion pressure and Release pressure as a function of voltage and for bipolar AC and DC drive. A quadratic fit of P = A V2 to the DC unipolar pressure versus V curve is shown, with A = (0.903 ± 0.17) *10–7 [kPa/V2] for adhesion and A = (2.29 ± 0.2) *10–6 [kPa/V2] for release. (c) and (d) Adhesion pressure and Release pressure as a function of voltage and for AC (1 Hz) and for DC drive with holding times of 10, 30 and 90 s.
