Patent ID: 8513531

Claim:
An electrodynamic array, comprising: a substrate; a multi-phase alternating current power source; a first electrode pattern comprising a first set of electrodes printed onto the substrate using ink comprising conductive nanomaterials, wherein the first electrode pattern is electrically connected to the power source to provide power to the first set of electrodes; and a second electrode pattern comprising a second set of electrodes printed onto the substrate using ink comprising conductive nanomaterials, wherein the second electrode pattern is electrically connected to the power source to provide power to the second set of electrodes that is out of phase with the power that the power source provides to the first set of electrodes; wherein the second set of electrodes is interleaved with the first set of electrodes on the substrate to repel dust from the surface when power is provided to the first electrode pattern and the second electrode pattern by the power source.
