Flow rate self-sensing of a pump with double piezoelectric actuators
Flow rate self-sensing of a classic pump with double piezoactuators is presented. The pump can concurrently perform fluid transportation and flow rate self-testing. A sensor is integrated onto the pump by segmenting the diaphragm?s electrode. The pump itself can reflect the optimal frequency by monitoring sensing voltage. The pump can be gotten only if any electrode of two piezoactuators is segmented.
