Harvesting Energy from Traffic Breakers using Piezoelectric Discs

With the rise in the demand for energy consumption, researchers are working on new means and ways to harness energy from various renewable sources. This research paper focuses on harnessing a new means of electrical energy by using piezoelectric technology. Piezoelectric discs were inter- connected and were embedded within a certain depth of the speed breaker which was capable of harvesting electrical energy from the transverse mechanical deformation of the piezo-discs by the sudden impact force caused by the automobiles passing through it is proposed. The piezoelectric discs were connected in series and parallel and embedded within a wooden plank which is enclosed with a rubber tyre and this arrangement was well placed within the speed breaker. On series of testing with the vehicular movement varying the impact loading over it was found that with small setup a maximum of 12.5 volt could be generated with a single vehicle movement.The energy harnessed was stored in the battery for later use like college campus lighting during night time. The motive of this project work is to obtain an alternate source of energy which is environment friendly and pollution free and hence, to utilize and optimize this energy being harnessed.
