Abstract:
An active electroadhesive cleaning device or system includes electrode(s) that produce electroadhesive forces from an input voltage to adhere dust or other foreign objects against an interactive surface, from which the foreign objects are removed when the forces are controllably altered. User inputs control the input voltage and/or designate the size of foreign objects to be cleaned. An active power source provides the input voltage, and the interactive 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 foreign objects of different sizes. Sensors can detect the amount of foreign particles adhered to the interactive surface, and reversed polarity pulses can help repel items away from the interactive surface in a timely and controlled manner.
