Design, fabrication and characterisation of free-standing thick-film piezoelectric cantilevers for energy harvesting
… vibration to electrical energy is the use of piezoelectric materials, typically operating as a cantilever in a bending mode, which generate a voltage across the electrodes when they are stressed. Traditionally, the piezoelectric materials are deposited on a non-electro-active substrate and are …
