AI Thread Summary
The discussion focuses on the design of piezoactuated micropumps using PVDF polymer actuators as membranes. The feasibility and cost-effectiveness of fabricating such devices are questioned, with suggestions to explore existing research on platforms like WebofScience or Google Scholar. There is a mention of the need to create microchannels and the importance of metallization for achieving electroosmotic or dielectrophoretic flow. The conversation highlights the experimental nature of the project, indicating that practical trials may be necessary. Overall, the discussion emphasizes the challenges and considerations in developing piezoelectric micropumps.

Hello!

I am intersting in microfluidic and especially micropumps with piezoelectrcially actuated membranes.
I would like to use PVDF polymer actuators and even try to use them directly as a membrane but I don't if it's possible and if the fabrication is feasible and cheap?

Could someone give some indications?

Thank you!

Do you mean in a similar fashion to how a peristaltic pump works? Maybe, but you'd probably need to try it. Or look and see if someone's already done it at, say, WebofScience or Google Scholar. Also, you'll probably have to figure out how to make microchannels in this stuff. I believe even when casting in PDMS or PMMA, you do metallization such that you can get electroosmotic (EO) or DiElectroPhoretic (DEP) flow.

EDIT: I am not an expert in microfluidic systems.

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
