Abstract
We report a novel technique for controlling the elastic coefficient of piezoelectric lead zirconate titanate (PZT) by connecting an electric circuit that behaves as a “negative capacitor” (hereafter referred to as negative-capacitance circuit). In this experiment, a PZT ceramic was connected with the negative-capacitance circuit. The attenuation factor in transmission loss from the ratio of the signal obtained using the system with the negative-capacitance circuit to the signal obtained without the negative-capacitance circuit was calculated. The attenuation factor in transmission loss was grater than 10 dB in the frequency range from 1 kHz to 100 kHz.
