Electroadhesion (EA) is an electrically controllable adhesion mechanism that has been studied and used in fields including active adhesion and attachment, robotic gripping, robotic crawling and climbing, and haptics, for over a century. This is because EA technologies, compared to other existing adhesion solutions, facilitate systems with enhanced adaptability (EA is effective on a wide of range of materials and surfaces), reduced system complexity (EA systems are both mechanically and electrically simpler), low energy consumption, and less-damaging to materials (EA, combined with soft materials, can be used to lift delicate objects). In this survey, we comprehensively detail the working principle, modeling, design, fabrication, characterization, and applications of EA technologies employed in robotics, aiming to provide guidance and offer potential insights for future EA researchers and applicants. Joint and collaborative efforts are still required to promote the in-depth understanding and mature employment of this promising adhesion and gripping technology in various robotic applications.

“…There is, therefore, a need for lighter, simpler and lower cost modular interconnection technologies. Electroadhesion (EA) [6] is an attractive and electrically controllable adhesion technology that has been widely employed in material handling [7][8][9][10][11], climbing robotics [12][13][14], and active attachment [15][16][17][18][19][20] applications due to the fact that: (1) EA pads can be produced using lightweight materials and simple structures, (2) the energy consumption of EA is low (in the range of mW), and (3) EA can be used on a wide range of surfaces and to lift almost any materials, including conductive and insulating materials. Electroadhesion is a controllable technology with potential for use in interconnecting lightweight modular robotics systems.…”

Reconfigurable smart structures and robots require interconnects that enable the transfer of forces, power and data from one modular element to another. This is typically achieved through magnetic coupling, mechanical clips and male-female electrical contacts. In lightweight structures however, these methods are impractical due to weight and complexity. In this work we present an electroadhesive coupling (EAC) controllable interfacial connection for joining lightweight modular components, which enable simultaneous mechanical joining and electrical pass-through connections for power and communication. Active adhesion and power transfer are realized by electroadhesion (EA) using conducting electrodes on lightweight materials such as papers. We present the underlying EAC concept, materials and structures, and demonstrate this new approach using origami and kirigami structures to fabricate a modular EAC bridge and a modular EAC cuboid structural interconnection system. These novel structures have the potential for application in lightweight robotics, space systems, deployable and self-assembling and self-disassembling systems.Supplementary material for this article is available online

“…Electroadhesion 1 is a promising and potentially revolutionary adhesion mechanism that can be employed to hold or grasp objects in domains such as space, high value manufacturing, robotics, and autonomous systems. Examples of where electroadhesion is in use include Electrostatic fixtures to hold work-pieces, 2 an adhesive method for space missions such as material handling 3 and controllable earth orbit grappling, 4 electrostatic chucks for material handling and grasping in semiconductor industries, 5 end effectors for gripping advanced composites and fibrous materials, 6 an adhesion mechanism for climbing 7 and flying 8 robots, and material handling units for manufacturing automation and warehouse automation applications. 9 This is due to certain advantages that electroadhesion has over other adhesion mechanisms such as pneumatic, magnetic, and bio-inspired methods.…”

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.
