摘要：

We have set up a model of a piezoelectric unimorph power harvester (PUPH). The PUPH consists of a piezoelectric layer and a metal layer. One end of the PUPH is fixed on a vibration base, the other end is connected by a concentrated mass. The PUPH scavenges energy from coupled extension and flexure vibration when excitation is inclined with the horizontal direction. We present a theoretical analysis on the basic behaviors of the PUPH by the theory of linear piezoelectricity. The theoretical results agree well with that of finite element method.
