Abstract
A mechanical energy harvester, such as for an electronic system such as a sensor system. The energy harvester has a spring with one end connected to a support structure, and a piezoelectric material on the spring. An electronics package is supported on the spring, the electronics package comprising at least one component selected from the group consisting of rectifier(s), storage component(s), and integrated circuit(s).
