  • Abstract
    The fabrication of a three-way valve on a silicon wafer by micromachining techniques is presented. The valve consists of two silicon wafers, a pyrex glass, and a piezoelectric actuator. This three-way valve can control gas flow or liquid flow with voltage applied to the actuator. The liquid flow can be controlled from 0.1 μl /min to 70 μl/min. The results from integrating the three-way valve with a micropump to produce a flow injection analyzing system are discussed
