This study is about a novel small piezoelectric pump. The pump utilizes a thin vibration plate on which bimorph type piezoelectric actuators generate progressive wave. Characteristics of the pump are investigated by experiments. It is observed that direction of flow depends on driving frequency and the direction does not always agree with phase of driving voltage signals applied to the piezoelectric elements. Behaviors of several part of the vibration plate in the pump case filled or not filled with water are investigated with laser Doppler vibration sensor. It is clarified that phase of sinusoidal vibration of the each part does not agree with the phase of driving signal. Interaction between vibration plate and water may cause the phenomenon.
