Design of a piezoelectric liquid pump

Click For Summary
SUMMARY

The discussion focuses on the design of a piezoelectric liquid pump utilizing RP printing for the structure and a PDMS diaphragm for the piezo device. The user seeks advice on suitable piezo materials that can deliver strong, high-amplitude variations. Concerns are raised regarding the effectiveness of medical check valves in maintaining flow direction under potential back pressure issues. Additionally, the user considers integrating a piezoelectric cleaner unit to enhance diaphragm isolation, emphasizing the need for a high-voltage driving circuit for optimal performance.

PREREQUISITES
  • Understanding of piezoelectric materials and their properties
  • Familiarity with RP (Rapid Prototyping) printing techniques
  • Knowledge of PDMS (Polydimethylsiloxane) applications in fluid dynamics
  • Experience with high-voltage circuit design for piezo devices
NEXT STEPS
  • Research suitable piezoelectric materials for high-amplitude applications
  • Explore advanced RP printing techniques for fluid pump structures
  • Investigate the design and implementation of medical check valves in fluid systems
  • Learn about high-voltage circuit design specifically for driving piezoelectric devices
USEFUL FOR

Engineers, product designers, and researchers involved in fluid dynamics, piezoelectric technology, and rapid prototyping will benefit from this discussion.

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.
