Piezoelelectric Nanogenerators for energy harvesting at traffic lights

The existing traffic lights systems as it is, still have many problems which can directly expose to danger the health of civilians and can even endanger their lives. The aim of the work was to suggest a solution to these problems and to show what potential might hold the piezoelectric nanogenerator technology and piezoelectric nanogenerator road pads in particular that are being developed by the Collective Usage Centre for Scientific Research "Nanomaterials and Nanotechnology" of the Grozny State Oil Technical University after acad. M.D. Millionshchikov. In order to so a new piece of nanogenerator technology in the form of road pads was presented in the work. The mini generators are being designed to harvest the mechanical energy of the moving cars at traffic lights and convert it to the electrical power using piezoelectric nanogenerators. The research is still in its initial phase, but the results gained already show promising power output of 6kW per cubic metre of the piezoelectric nanogenerator area. The output power currently is not enough to create traffic lights system independent from the electrical public network, however the integration of the two power sources is considered possible.
