Abstract
Disclosed are methods, devices, apparatuses, and systems for poling a piezoelectric film. A poling system can be a corona poling system including a corona source with one or more corona wires configured to transfer a corona discharge onto a major surface of the piezoelectric film. The poling system can further include a grid electrode interposed between the corona source and the piezoelectric film. A substrate including the piezoelectric film may be supported on a substrate support, where the substrate and the corona source are configured to move relative to each other during poling.
