An experimental investigation into the relationship between the interfacial electroadhesive force and applied voltage up to 20 kV has been presented. Normal electroadhesive forces have been obtained between a double-electrode electroadhesive pad and three optically flat and different substrate materials: glass, acrylic, and polycarbonate. The results have shown that not all substrate materials are good for the generation of electroadhesive forces. Only 15.7 Pa has been obtained between the pad and the polycarbonate substrate under 20 kV, whereas 46.3 Pa and 123.4 Pa have been obtained on the acrylic and glass substrate, respectively. Based on the experimental data, empirical models, with an adjusted R-square value above 0.995 in all cases, have been obtained for the three substrates. However, it has not been possible to develop a general empirical model which is suitable for all substrates. This further indicates the need for a large quantity of experimental data to obtain robust empirical models for different substrate materials in order to reliably use electroadhesive technologies for material handling applications.

“…The electrode dimensions of the concentric and spiral pads were the same as the ones published previously. 17 They were also tested using the electroadhesive "normal force" testing platform and procedure published previously. 11,19 In order to eliminate the effect of the dielectric thickness and surface texture on the adhesive force obtainable, during the tests, the PET side of the pads was used to face the Al substrate.…”

Current electroadhesive actuators cannot produce stable electroadhesive forces on the same substrate with different interfacial surface interactions. It is, therefore, desirable to develop electroadhesive actuators that can generate stable adhesive forces on different surface conditions. A symmetrical electroadhesive pad that is independent of different interfacial scratch directions is developed and presented. A relative difference of only 6.4% in the normal force direction was observed when the electroadhesive was facing an aluminium plate with surface scratch directions of 0°, 45°, 90°, and 135°. This step-change improvement may significantly promote the application of electroadhesion technology. In addition, this manifests that significant performance improvements could be achieved via further investigations into electroadhesive designs.

The growing need for automation in industries has foreseen drastic advancements in the development of soft robotics in the areas of navigation systems, textiles, healthcare, and biometric monitoring. Electroadhesion (EA)‐based robotic applications benefit from ultralow power consumption, low maintenance, choices in versatile surfaces, sustainable life cycles, applicability in harsh and vacuum environments, and exteroceptive/proprioceptive abilities. It is of scientific and technological importance to comprehend the sequence of developments in working mechanisms, modeling, and materials to explore its full potential for future intelligent robotics systems. This review provides an all‐inclusive roadmap of EA technology from its inception to unprecedented developments and complex relationships across multidisciplines, viz., robotics, solid and fluid mechanics, electrostatics, haptics, space technologies, nanotechnology, and IoT.
