| Abstract: | In this paper, the structure and working principle of valveless micropump actuated by SMA/Si (NiTi/Si) diaphragm was introduced. Mathematic model was build and the pressure and flow rate of the micropump were simulated with Matlab. The simulation result and the experimental result were compared. The influence of the driving frequency and the geometry of the pump on the performance of the micropump was analyzed and the optimization scheme of the micropump was obtained. |
