Abstract:
An electroadhesive cleaning device or system includes electrode(s) that produce electroadhesive forces from an input voltage to adhere debris against an electroadhesive surface, from which the debris is removed when the forces are controllably modified. Controlling the input voltage may designate the size of debris to be cleaned. A power source provides the input voltage, and the electroadhesive surface can be a continuous track across one or more rollers to move the device across a dirty foreign surface. Electrodes can be arranged in an interdigitated pattern having differing pitches that can be actuated selectively to clean debris of different sizes. Sensors can detect the amount of debris adhered to the electroadhesive surface, and reversed polarity pulses can help repel items away from the electroadhesive surface in a controlled manner.
