| titleOfInvention | Piezoelectric device and method for using same |
| abstract | A piezoelectric device, which has bipolar polarization-electric field (Pr-E) hysteresis characteristics of a piezoelectric material asymmetrically biased, when a first and second coercive electric fields respectively having smaller and larger absolute values are defined as Ec1 and Ec2 and a bias ratio of the coercive electric field is defined as [(Ec2+Ec1)/(Ec2−Ec1)]×100[%], includes a piezoelectric element unit including a piezoelectric body film whose bias ratio is 20% or more, the piezoelectric element unit operating with an electric field intensity smaller than that of the first coercive electric field. The piezoelectric device includes a refresh voltage applying circuit configured to apply a voltage to maintain operation performance of the relevant device, the voltage having an electric field intensity larger than the electric field intensity for operating the device and being equal to or less than three times |Ec1|, such that a polarized state of the piezoelectric body film is restored. |
