摘要: Abstract To better understand how the electric power generated from PZT piezoelectric ceramics is affected by mechanical loading conditions generation was examined during cyclic under various conditions. The continuously using a monitoring system that we have recently developed. This revealed increased with increase of applied load but then decreased when exceeded certain level. In addition, greater simple beam configuration compared cantilevered beam. change directly related to stress direction; high in tetragonal structure parallel c -axis gave rise generation. On other hand, material failure, including domain switching and crack generation, caused reduction generated. Based upon our experimental data, suitable give energy been clarified.
