英文摘要：

In order to improve the work efficiency of a piezoelectric pump, an insulated bimorph with double functions was proposed through insulation process of bimorph. The insulated bimorph as a driving component of piezoelectric pump could be curved in two directions and could form the outputs. A piezoelectric pump＇s structure with double functions was obtained by making an insulated bimorph into two antrums. Some elastic curved surface differential equations of insulated circular piezoelectric composite laminates were derived from the elastic thin plate bending theory based on small deflection, and the project and course of insulated process of bimorph were introduced and analyzed. The experimental results show that the insulated bimorph not only has insulated characteristic but also has favorable tenacity and considerable intensity. The breaking voltage of bimorph can increases more 20-30 V than that of uninsulated bimorph, which shows that a new piezoelectric component with double functions is offered for correlative manufacture and scientific research.
