Electric Energy Scavenger Device

摘要

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.
