Abstract
Piezoelectric inkjet is a kind of device which can achieve drop-on-demand and has the advantages of high injection precision, fast response, and good stability. Nowadays, the piezoelectric inkjet technology has been widely used in various industrial fields. In this paper, the applications of piezoelectric inkjet in different industries are reviewed and summarized. In order to make the piezoelectric inkjet to perform stable and high-performance work, the parameters that affect the injection performance are analyzed by researchers and recommended parameters are given depend on the analyzing results. There are many parameters that influence the injection performance, such as excitation parameters, fluid physical parameters, structure size and bubbles. And the useful methods for analyzing the effect of different parameters are reviewed and discussed. Besides, the corresponding analysis results are also summarized.
