Abstract
The present invention is concerned with an electricity generator. The generator resembles a transistor and powered by impacting liquid such as water droplets. The generator has a glass substrate defining an upwardly facing surface and a downwardly facing surface. The substrate includes i) a region with polytetrafluoroethylene (PTFE) coated on the upwardly facing surface and acting as a virtual source and ii) an electrode arranged adjacent said PTFE coated region on the upwardly facing surface and acting as a drain in that the PTFE coated region and the electrode are positioned on the upwardly facing surface to receive an impacting water droplet acting as a gate, and wherein circuitry of the generator connects the virtual source and the drain via an electrical connection passing the downwardly facing surface, and electricity is harvested via the electrical connection.
