From: Measuring electro-adhesion pressure before and after contact
(a) EA test bench consisting of a force sensor, a target object (conductive or dielectric), an EA patch with interdigitated electrodes, and a multi-axis stage (b) Electroadhesion for conductive and dielectric objects. The EA force (red arrow) is normal to the EA patch in both cases, but the electric field distributions are different, with fringing fields playing an essential role in the case of a dielectric object.
