英文摘要：

A piezoelectric-stack pump prototype was designed and manufactured to realize high-precision,microscale and automation dispensing of reagents.The structure and working process of the piezoelectric-stack pump were discussed.The key components to the pump＇s function for non-contact micro-reagents dispensing were analyzed in theory and simulation with finite element analysis software both statically as well as dynamically.The output characteristics of the piezoelectric-stack pump were studied.The precision and repeating precision for piezoelectric-stack pump and reagents dispensing were tested respectively.Experiment result showed that the piezoelectric-stack pump could meet the requirements of fast micro-reagents dispensing with accuracy.
