“…They have received extensive attention because of their potential applications in biomedical devices, biological and chemical analysis, microelectronics cooling, fuel-drop generator for automobile heaters and space exploration [1][2][3]. Many piezoelectric pumps are developed using piezoelectric membrane actuators (named also piezomembrane pumps) for liquid delivery.…”

Abstract. : Piezo-pumps, in the last decade, have received extensive attention because of their potential applications in biomedical devices, biological and chemical analysis, micro-electronics cooling and space exploration. In this paper an analytical model is developed to analysis the parameters effect on the pump flow. The micro-pump driven by piezostack (PZT alloy multilayer) as actuator is studied as function size and working middle. This one is compared with SCMCP pump actuated by PZT alloy as piezomembrane.The flow change as a function frequency, the chamber diameter and control voltage are analyzed. The simulation results obtained with two different liquids (water and blood) as working middle are discussed and compared with experimental results. The results are satisfactory.

“…Active properly phased valve control is achieved by a miniature solenoid valve connected in series with the transformer primary winding and a rectangular-wave generator. Further development led to a pump (SPENCER et al, 1978) which in addition has piezoelectric valves to reduce power consumption. The piezoelectric pump and valves system has three chambers, an inlet chamber connected to the insulin reservoir, a pump chamber and an outlet chamber connected to the patient's body.…”

“…After the classification of various valveless piezoelectric pumps with cone-shaped tubes and the functional analysis of each type, researchers will also endeavor to shape the future development and implications. [10][11][12][13][14][15][16][17][18], and applying the concept that the coneshaped tube can be regarded as dynamic passive valve [2], Stemme proposed the valveless piezoelectric pump with cone-shaped tubes in 1993, and subsequently patented their design. The diffuser (a) and nozzle (b) of this pump are sketched in Fig.…”

This paper reviews the development of valveless piezoelectric pump with cone-shaped tube chronologically, which have widely potential application in biomedicine and micro-electro-mechanical systems because of its novel principles and deduces the research direction in the future. Firstly, the history of valveless piezoelectric pumps with cone-shaped tubes is reviewed and these pumps are classified into the following types: single pump with solid structure or plane structure, and combined pump with parallel structure or series structure. Furthermore, the function of each type of cone-shaped tubes and pump structures are analyzed, and new directions of potential expansion of valveless piezoelectric pumps with cone-shaped tubes are summarized and deduced. The historical argument, which is provided by the literatures, that for a valveless piezoelectric pump with cone-shaped tubes, cone angle determines the flow resistance and the flow resistance determines the flow direction. The argument is discussed in the reviewed pumps one by one, and proved to be convincing. Finally, it is deduced that bionics is pivotal in the development of valveless piezoelectric pump with cone-shaped tubes from the perspective of evolution of biological structure. This paper summarizes the current valveless piezoelectric pumps with cone-shaped tubes and points out the future development, which may provide guidance for the research of piezoelectric actuators.
