sentences:  Clamping pressures in the range of 0.5 to 1.5 N/cm2 (0.8 to 2.3 psi) have been claimed.An electroadhesive pad consists of conductive electrodes placed upon a polymer substrate.When alternate positive and negative charges are induced on adjacent electrodes, the resulting electric field sets up opposite charges on the surface that the pad touches, and thus causes electrostatic adhesion between the electrodes and the induced charges in the touched surface material.
