The fluid is flowed through the action of the piezoelectric element in the arc-shaped curved pipe, affected by the centrifugal force and Coriolis force. According to this phenomenon, a valveless piezoelectric pump with an arc-shaped tube is developed. Based on the inverse piezoelectric effect of the piezoelectric element, the volume of the pump chamber periodically changes. Due to the Earth′s rotation, the flow resistance of the fluid differs between the clockwise and counterclockwise flow status, and thus a macro one-way flow is formed. The differential pressure test of the prototype shows that when the driving voltage is 130 V and the driving frequency is 14 Hz, the pressure drop reaches the maximum value of 17 mm H20, whilewhen the driving frequency is 30 Hz, the pressure drop is reduced to 3 mm H20. The pressure drop is generated from the Coriolis force of the Earth′s rotation, and the rotational speed of the overall structure of the pump can be reflected by the amplitude of the flow or the differential pressure. Therefore, local geographical information can be acquired by measuring the Earth′s rotational speed, forming a new principle of navigation.
