A simplified theory of "stickiness" due to electroadhesion between rough surfaces

Building on theories of Persson, we derive a simpler theory for electroadhesion between rough surfaces using BAM (Bearing Area Model) of Ciavarella, or previous ideas by Persson and Tosatti. Rather surprisingly, in terms of stickiness, we obtain very simple and similar results for pure power law power spectrum density (PSD), confirming stickiness to be mainly dependent on macroscopic quantities. We define a new dimensionless parameter for electroadhesive stickiness.
