Electromechanical characteristics of piezoelectric converters with freely defined boundary conditions and geometry

摘要

Piezoelectric converters are used to measure and/orregulate a wide range of physical parameters such as force[1], strain [2], pressure [3], acceleration [4]. These are alsoused as resonators [5] or even diaphragm drives [6]. Theirworking principle is based on conversion of electric energyto the mechanical, or vice versa [7]. Dependency betweenstrain and electric field is defined by constitutive equation[8, 9]
