摘要： A method and apparatus is provided for measuring mechanical and electrical properties of specimens, in particular transducer properties (e.g., electromechanical coupling constant) of piezoelectrics. Three measurement specimens each of the same material and the same dimension and having parallel planes, and two insertion plates each of the same material and the same dimension and having known mechanical properties, are stacked alternately, a load is applied to these measurement specimens and insertion plates via the outer measurement specimens, displacements in the direction of application of the load are measured before and after application of the load, and an elastic constant of the middle measurement specimen is determined based on those displacements. Measurement of the electromechanical coupling constant of piezoelectric specimens is achieved using the same apparatus under short-and-open circuit conditions.
