Electroadhesion

Electroadhesion

Electroadhesion is the term given to the electrostatic effect of astriction between two surfaces subjected to an electrical field. Applications include the retention of paper on plotter surfaces, astrictive robotic prehension (electrostatic grippers) etc. Clamping pressures in the range of 0.5 to 1.5 N/cm2 (0.8 to 2.3 psi) have been claimed.

Electroadhesion can be loosely divided into two basic forms: that which concerns the prehension of electrically conducting materials where the general laws of capacitance hold (D = E ε) and that used with electrically insulating subjects where the more advanced theory of electrostatics (D = E ε + P) applies.
