Abstract

See full text

A piezoelectric device includes a piezoelectric element including a first electrode, a second electrode, and a piezoelectric layer provided between the first electrode and the second electrode, and a driving system that drives the piezoelectric element by applying voltage to the first electrode and the second electrode, in which the driving system drives the piezoelectric element at a maximum voltage that is lower than a voltage at which a tunnel current or a Poole-Frenkel current starts to be generated in the piezoelectric element.
