Abstract:
Considering the advantages and disadvantages of reported micropumps, we aimed to introduce a novel idea to diminish the disadvantages and promote the advantages of PiezoElectric micropumps. This novel idea operates based on a mercury slug actuation in a microchannel. This cyclic motion of the mercury slug which is similar to a piston, push the fluid in the microchannel and pump the flow. However, to bring this idea into the practice, a control system must be designed. This system contains: LABVIEW code, DAQ board & a switching Board. The pattern of actuating mercury is drawn in LABVIEW. DAQ Board produces electrical signals according to LABVIEW code. Switching board will transform the electrical signals to electrical current that can actuate mercury slug. At the experimental result section the impact of several dimensions in the performance of micropump can be discussed. But here only frequency is studied. Also, characteristic curve of mercury micropump is achieved that shows changes in the flow of the micropump are investigated versus the pressure difference
