Energy harvesting from a five-story building and investigation of frequency effect on output power

Human activities on the building floor can cause vibration which is potentially disturbing for occupants. This kind of vibration could be useful in energy harvesting. One of the most important devices for energy harvesting is piezoelectric materials. In this paper the energy harvesting of a five-story wooden building vibration using piezoelectric materials is developed and a new fixture is designed for piezoelectric energy harvester. Furthermore, the effect of frequency on output energy is investigated and the power of energy harvesting is obtained. Results show that increasing of input frequency leads to increase the energy harvesting from Volture.
