在生醫檢測上，為了達到減少試劑用量和實現快速及多功能性平行檢測之目的，微小化已是不可避免的趨勢，各項生醫檢測用途之大型機台預期未來可被生醫晶片部分取代。整合移動、混和、切割、產生、取樣等功能後，更可以實現實驗室晶片(Lab on a Chip)的概念。
本研究旨在實現開放式數位微流體回授控制系統，利用導線式(Catenary)數位微流體元件之感測電容值作為回授機制，可以實現液滴即時位置判斷及控制處理來避免因製程、人為或環境等因素不完美所造成無法順利操作之情形，並於液滴移動困難時以重複驅動配合增加施加電壓之方式進行補償，以提升控制之可靠度。
本研究完成導線式數位微流體元件之晶片製程，並以自行設計之載台進行液滴操控實驗，配合電容回授電路及LabVIEW人機介面控制器，最後展示全系統採自動化電容回授控制後之成果，並探討此系統的未來展望，以期成為未來生醫研究領域之利器。
