Abstract
A method of making an actuator for a resonant acoustic pump comprises: forming a through-hole in a ceramic material of a piezoelectric layer of the actuator, prior to assembly of the piezoelectric layer with other layers of the actuator; forming a through-hole in a flexible circuit layer of the actuator; forming a through-hole in an end plate layer of the actuator; and disposing each of the piezoelectric layer and the end plate layer on a respective one of opposite sides of the flexible circuit layer, so that the through-holes align to provide a passageway for a fluid to pass through the actuator.
