使用非线性屈曲梁的压电能量收集及其方法
Abstract:
本发明公开了一种能量收集器，所述能量收集器包括框架，所述框架具有底座、附连到所述底座的第一侧构件，和附连到所述底座并与所述第一侧构件间隔开的第二侧构件。梁联接在所述框架的所述第一侧构件和所述框架的所述第二侧构件之间。所述梁具有基底层，所述基底层具有附连到所述框架的所述第一侧构件的第一端部、附连到所述框架的所述第二侧构件的第二端部、第一面、和与所述第一面相对的第二面。所述基底可响应于振动力而弹性变形。所述梁还包括第一压电层，所述第一压电层接合到所述基底层的所述第一面并具有用于电连接到负载的端子，所述第一压电层包括至少一个压电贴片。
Abstract(English):

An energy harvester includes a frame having a base, a first side member affixed to the base, and a second side member affixed to the base and spaced apart from the first side member. A beam is coupledbetween the first side member of the frame and the second side member of the frame. The beam has a substrate layer with a first end affixed to the first side member of the frame, a second end affixedto the second side member of the frame, a first face, and a second face opposite to the first face. The substrate is elastically deformable in response to the vibratory force. The beam further includes a first piezoelectric layer joined to the first face of the substrate layer and having a terminal for electrical connection to a load, the first piezoelectric layer comprising at least one piezoelectric patch.
