ABSTRACT:
The elastic modulus of a piezoelectric substance is controlled over a wide range using a simple method. The effective modulus (the real part of the elastic modulus) and the energy loss modulus (the imaginary part of the elastic modulus) of the piezoelectric substance are changed by installing electrodes on the surface of the piezoelectric substance and by connecting a mechanism consisting of one or more circuit elements to each of the electrodes.
