本文利用自行發展的驅動觀測系統，以控制訊號輸出的實驗方式，來觀察擠壓管型壓電式噴印頭噴射液滴成型之過程。藉由電腦程式產生不同的脈衝電壓訊號與延遲訊號參數，使用電荷耦合攝影機拍攝噴頭噴孔介面變化以及液滴形成的過程，利用影像擷取系統處理量測研究這些訊號參數對於液滴出口速度、液滴體積，分析討論收縮管型壓電式噴印頭內部壓力傳遞，利用本論文的實驗結果，瞭解其內部壓力波傳遞限制條件，尋找出有效驅動波型以及作動參數條件，達到精確控制收縮管型壓電式噴墨頭的目標。在實驗量測中，可為製作新型噴頭時的參考。

　　Over the past twenty years, ink-jet printing technology has not only become a dominant player in the low cost color printer and industrial marking markets, it has become accepted as a precision microdispensing technology. With this broader viewof the technologies encompassed by the term ink-jet, applications in electronics, optics, displays, virtual reality, medical diagnostics, and medical procedures have been developed using ink-jet fluid microdispensing as an enabling technology.
　　This paper aims to experiment and analyze the ejection behavior of droplets created by a squeeze mode piezoelectric inkjet printing device .The piezoelectric driven printing system has been developed in this study to drive and observe different pulse voltage pattern and delay time .To discuss the effects of operating frequency ,pulse time ,pulse voltage ,pulse type, positive voltage keeping time and pulse voltage magnitude on the volume and velocity of the droplets .Looking for the best droplet form in order to exact control piezoelectric print-head and confirming that it is reliable piezoelectric print-head driven and imaging system.
