Chung Hua University is a private university located in Xiangshan District, Hsinchu City, Taiwan. It was formerly known as Chung Hua Polytechnic Institute founded in 1990 by three local Hsinchu entrepreneurs, Ron-Chang Wang, Zau-Juang Tsai and Lin Junq-tzer. It was upgraded to university status and renamed as "Chung Hua University" in 1997. There are six colleges with 25 departments offering undergraduate courses as well as 16 master programs and 3 PH.D. programs. Wikipedia.

A nozzle device includes an upper cover module having a cavity, a plurality of stacked piezoelectric plate modules, a plug module, and a lower cover module. Each piezoelectric plate module includes a substrate, a piezoelectric material, an electrical connection, an upper electrode, and a lower electrode. The substrate includes multiple first through holes disposed correspondingly to the cavity. The piezoelectric material is located on the upper surface of the substrate. The electrical connection extends from the lower surface of the substrate, through the substrate, and to the bottom of the piezoelectric material. The lower electrode is located below the lower surface of the substrate and electrically connects to the electrical connection. The plug module includes plugs and second through holes corresponding to the first through holes. The lower cover module includes openings disposed according to the plugs of the plug module.
