Abstract
An electroadhesive clutch using a ceramic-based dielectric layer separating opposing clutch plates, which function as electrodes. At least one of the clutch plates can be a flexible material, such as a thin film. A voltage applied across the electrodes creates an electrostatic attraction between the electrodes. The ceramic-based dielectric layer can be applied to one or both electrodes or, alternatively, placed between opposing electrodes. The ceramic-based dielectric reduces the voltage required to adhere adjacent plates, while also improving the force of adhesion. A rotary electroadhesive clutch using the ceramic-based dielectric provides improved force of adhesion and can be used to control the amount of torque transferred from an input to an output.
