The Structure Design Techniques of the Embedded Piezoelectric Power Generating Device in Intelligent Building

Article Preview

Abstract:

Directly scavenging vibration energy from ambient environment to power terminal micro sensors in intelligent building is a rising way to face the energy supply problem. The four distinct advantages of embedded piezoelectric harvester as an appropriate power supplier of the terminal sensors are introduced. The structure designing techniques include mode and geometry design, frequency shift methods, real power-density are analyzed. The 31 mode type harvester with PZT material and cross-distributing structure are highly recommended.
