Piezoresponse in Mesoscale Doped Barium Titanate Perovskite – A New Avenue of Energy Harvesting

Energy-harvesting from pedestrian infrastructure is new research territory that encompasses technology which captures the waste kinetic energy generated while walking, something that can be accumulated and stored for later use. These enticing characteristics can be offered by extended paver surfaces with the more options of collecting effective mechanical pressure as input and their output can be listed as production of electrical energy. The objective of this project is to develop and test of a robust thin film using highly strained, ferroelectric multilayered Barium Titanate (and its variation) on reinforced substrate with high stack density and bring this material into application after sequential scientific investigation.
