Abstract
A device for harvesting and storing triboelectric charge generated on an exterior surface of a moving vehicle is provided. It is characterised by comprising;
- a supercapacitor comprised of nano-carbon-containing electrodes; an ionic liquid electrolyte and at least one ion-permeable porous membrane;at least one first element exposed to aerodynamically-induced frictional forces acting thereon and on which the charge is caused to build up and connected to at least one of the electrodes of one polarity;at least one second element having a lower electrostatic potential than the charge-collecting element and connected to at least one of the electrodes of the other polarity;a voltage modification or impedance conversion circuit arranged between the first and/or second elements and the supercapacitor;means to connect the device to an operative component requiring electrical power anda controller for managing the performance of the device and switching between energy-harvesting and energy-utilisation modes.
