Valveless piezoelectric pump has low-cost and easy miniaturization characteristics, and its important development trend is multi-function integration. The current paper reports a new phenomenon that the flow in a spiral tube element is sensitive to the element attitude caused by the Coriolis force, and that a valveless piezoelectric pump is designed by applying this phenomenon. The valveless piezoelectric...
