    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 clot-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 piezoelectric cooling chamber and method for providing the cooling system are described. The cooling chamber includes a piezoelectric cooling element, an array of orifices and a valve. A vibrational motion of the piezoelectric cooling element causes an increase or decrease in a chamber volume as the piezoelectric cooling element is deformed. The array of orifices is distributed on at least one surface of the chamber. The orifices allow escape of fluid from within the chamber during the decrease in the chamber volume in response to the vibration of the piezoelectric element. The valve is configured to admit fluid into the chamber when the chamber volume increases and to substantially prevent fluid from exiting the chamber through the valve when the chamber volume decreases.

    Abstract: A flow chamber having an upper chamber, a lower chamber, and an actuator is described. The upper chamber includes a top wall. The actuator is located distally from the top wall. The lower chamber includes a bottom wall and a sidewall. The lower chamber receives a fluid from the upper chamber when the actuator is activated. The bottom wall has orifices and at least one cavity therein. The orifices are vertically aligned with a portion of the actuator and allow the fluid to exit the lower chamber. The at least one cavity is proximate to the sidewall and distally located from the orifices.
