An electrically conductive patch for a sheet that is part of a skin of an aircraft is disclosed. The sheet includes an outermost surface constructed of an electrically conductive material and one or more electrical discharge points that are conductively coupled to the outermost surface of the sheet. The electrically conductive patch is disposed along the outermost surface of the sheet and is conductively coupled to the outermost surface of the sheet. The electrically conductive patch is constructed of a voltage responsive film configured to change from a first coloration and into a second coloration in response to experiencing a threshold voltage difference, where the first coloration substantially matches a coloration of the skin of the aircraft.

Ion Harvesting Technology harvests high voltage electricity, including from atmospheric ions. A wire, or conductive tether, may be used to connect ion harvesting material (typically carbon, but including any materials such as metals, metamaterials, or others) located on or near an aerial platform to an anchor point. Because the harvested electricity is typically of high voltage, the electricity may arc between the conductive tether to nearby points of lesser or greater voltage. Such arcing represents a loss of power to the overall system, causing the overall system to be less efficient, or possibly non-operational, and in some cases may cause catastrophic system failure. Electrical isolators may be used to prevent the losses from the arcing.
