Abstract: Described herein is an apparatus, comprising a substrate having a top surface and a bottom surface. In an embodiment, the apparatus comprises one or more piezoelectric transducers having a diameter of about 10 mm and a thickness of about 2 mm, embedded in the substrate. In an embodiment, the apparatus comprises one or more cavitation chambers having a depth of about 1 mm, each of the one or more cavitation chambers disposed between respective ones of the one or more piezoelectric transducers and the top surface of the substrate, wherein the one or more piezoelectric transducers generate vibrations within a frequency range about 20 kHz to about 1 MHz in the cavitation chambers that cause a substance stored in the cavitation chambers to be forcibly moved through the top surface of the substrate.
