Design of a piezoelectric liquid pump

[miva]

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 I am thinking of using medical check valves to be able to build a flow in one direction but i think there won't 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.
