We all know that, piezoelectric energy harvesting is a relatively new and specific topic as far as other energy sources are concerned. And as much as we can, scientists have tried and are trying to harness sufficient energy from these materials which only give relatively small output. So as far as we using PZT ceramics (Lead Zirconate Titanate) as a material for our tiles or slabs, can we really achieve something ? Any advice on this or articles or paper recommendations ?
