Analysis of Rosen type energy harvesting devices from porous piezoceramics with great longitudinal piezomodulus

This paper describes analytical and numerical modeling of the energy harvesting device based on composite piezoelectric materials. The device is a nonuniformly polarized porous piezoceramic compound plate such as a Rosen‐type piezoelectric transformer with single bimorph section. The effective prope...
