Abstract
Energy harvesting systems and devices are provided that harvest energy from external asynchronous force impulses using fluidic force transfer of the external force impulses to a plurality of compliant piezoelectric layers that seal a corresponding plurality of inner cavities. Each inner cavity can contain a compressible gas. Direct fluidic force transfer can be accomplished via a compressible or incompressible fluid between an external cover and the compliant piezoelectric layers.
