Patent ID: 8881994

Claim:
A synthetic jet actuator comprising: a first plate; a second plate spaced apart from the first plate and arranged parallel thereto; and a spacer element configured to space the first plate apart from the second plate and defining a chamber along with the first and second plates, the spacer element having at least one orifice formed therein such that the chamber is in fluid communication with an environment external to the chamber; wherein the spacer element forms a lateral side-wall of the chamber and the first and second plates form respective top and bottom walls of the chamber; and wherein the spacer element is constructed to deform in an inward and outward bending motion in response to a deflection of at least one of the first and second plates, the inward and outward bending motion being in a direction perpendicular to a direction of the deflection of the at least one of the first and second plates.
