Abstract
A method for electrically setting a gap for a piezoelectric pressure sensor. The method includes positioning a piezoelectric flex element on a tray; attaching a voltage source to the piezoelectric flex element of a piezoelectric pressure sensor; applying a voltage from the voltage source to the piezoelectric flex element; curing an adhesive between the piezoelectric flex element and the tray while the piezoelectric flex element is deflected by the voltage; and stopping the voltage from the voltage source to the piezoelectric flex element when the adhesive has been cured.
