Abstract: A piezoelectric cooling system and method for driving the cooling system are described. The piezoelectric cooling system includes a first piezoelectric cooling element and a second piezoelectric cooling element. The first piezoelectric cooling element is configured to direct a fluid toward a surface of a heat-generating structure. The second piezoelectric cooling element is configured to direct the fluid to an outlet area after heat has been transferred to the fluid by the heat-generating structure.

Abstract: A method for providing a piezoelectric device is described. The method includes providing a first electrode layer on a substrate and coating at least one layer of piezoelectric material. The coating using at least one of slot-die coating, dip coating, aerosol coating and R2R coating such that a layer of the at least one layer of piezoelectric material has a variation in thickness of not more than ten percent. The layer(s) of piezoelectric materials are also heat treated. Multiple layers of piezoelectric material may be slot-die coated and heat treated to provide a multilayer having the desired thickness. A second electrode layer is provided on the layer(s) of piezoelectric material.

Abstract: A method for providing a cooling system is described. The method includes providing a plurality of sheets. Each sheet includes at least one structure for a level in each cooling cell of a plurality of cooling cells. A particular level of each cooling cell includes a cooling element having a first side and a second side. The cooling element is configured to undergo vibrational motion to drive fluid from the first side to the second side. The method also includes aligning the sheets, attaching the sheets to form a laminate that includes the cooling cells, and separating the laminate into sections. Each section includes at least one cooling cell.
