Design of a piezoelectric liquid pump

  1. Jul 9, 2009 #1
    Hey guys

    im in the process of designing a piezoelectric liquid pump, i am looking to make the structure out of RP printer for now and use a PDMS diagrphram for the piezo device to be mounted apon. Have any of you guys worked with piezo materials before as i am in need of a strong high amplitude varying one.

    Also im thinking of using medical check valves to be able to build a flow in one direction but i think there wont be enough back pressure to keep them tightly sealed.

    Any opinions would help very much!

    How about a piezoelectric cleaner unit to make the isolations to the diaphragm as this piezo devise is very strong but you would have to make a circuit to drive it at high voltage.
