An electroadhesion gripper is a robotic end-effector that uses electrostatic attraction to adhere to an object’s surface. By applying an electric voltage to an array of electrodes, the gripper generates an electrostatic field that induces opposite charges on the target object, creating a strong adhesive force. This method allows the gripper to pick up and manipulate objects gently, without mechanical clamping that can cause damage.
Unlike magnetic grippers, which are limited to ferromagnetic materials, electroadhesion grippers can handle a vast range of materials, including non-metallic, soft, and delicate surfaces such as glass, plastic, thin films, fabrics, and semiconductor wafers.
