Abstract: An exemplary energy harvester includes a piezoelectric diaphragm, an eccentric mass that rotates in response to external motion, and a piezoelectric stress inducer coupled with the eccentric mass and the piezoelectric diaphragm. The piezoelectric stress inducer deforms the piezoelectric diaphragm in response to rotational motion of the eccentric mass, causing the piezoelectric diaphragm to generate electrical energy.

Abstract: An electric energy scavenger device has a housing forming an internal chamber with an internal wall, and a movable element contained within the internal chamber. The movable element is freely movable and unconnected to any other movable element within the internal chamber. Within the internal chamber, the device also has a plurality of piezoelectric charge conversion elements positioned along the internal wall. The plurality of piezoelectric charge conversion elements are positioned side-by-side to contact the movable element when the movable element moves within the internal chamber. In addition, the movable element is configured to simultaneously contact at least two of the plurality of side-by-side piezoelectric charge conversion elements. During use, the movable element is freely movable within the internal chamber in response to movement of the entire housing.

Abstract: A capped micromachined device has a movable micromachined structure in a first hermetic chamber and one or more interconnections in a second hermetic chamber that is hermetically isolated from the first hermetic chamber, and a barrier layer on its cap where the cap faces the first hermetic chamber, such that the first hermetic chamber is isolated from outgassing from the cap.
