ABSTRACT:
In some embodiments, piezoelectric air jet augmented cooling for electronic devices is presented. In this regard, an apparatus is introduced having a plurality of more than about one hundred lead-free piezoelectric layers and electrodes stacked on top of each other and formed around a central opening, and a diaphragm coupled to the piezoelectric layers and substantially covering the central opening to vibrate and blow air when an operating voltage is applied to the electrodes. Other embodiments are also disclosed and claimed.
