Abstract
A method for monitoring polarization quality of a piezoelectric film is described. In this method, a detection step is performed on a piezoelectric film by using a detection device with a non-contact method during a polarization process of the piezoelectric film, to obtain a static electricity information or a transmittance information. A determination step is performed by using the static electricity information or the transmittance information to determine a polarization degree of the piezoelectric film.
