Discussion Overview

The discussion centers around sourcing piezoelectric materials, specifically for experiments aimed at generating electricity. Participants are exploring options for flexible and affordable materials suitable for various experimental setups.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant seeks recommendations for easily bendable and inexpensive piezoelectric materials for experiments.
  • Another participant suggests purchasing piezo actuators from a specific supplier and offers to recommend other sources if needed.
  • A third participant mentions that Goodfellow sells polyvinylidene fluoride (PVDF) film, describing its potential use in creating sensors or generators with a simple setup involving conductive copper tape.
  • A question is raised about the thickness of PVDF film and its bondability with glass.
  • One participant shares their experience using a metallised biaxial sheet and Mylar PET as an insulating substrate, noting the creation of a thin, flexible load cell.
  • Several participants express interest in obtaining schematics or papers from another participant regarding their piezoelectric setup, indicating a desire for more detailed information on the methods used.

Areas of Agreement / Disagreement

Participants generally agree on the interest in piezoelectric materials and their applications, but there are no settled views on the best sources or methods for using these materials, indicating multiple competing perspectives and ongoing inquiries.

Contextual Notes

Some discussions involve specific material properties and bonding capabilities, which may depend on individual experimental setups and requirements. There are also requests for additional information that remain unresolved.

Who May Find This Useful

Individuals interested in experimental physics, materials science, or engineering applications related to piezoelectricity may find this discussion beneficial.

I'm wanting to do some experiments with creating electricity from piezoelectric materials but I'm not sure where I can buy some. I'm looking for some materials that are easily bendable like paper and preferably cheap as I have several experiments I'd like to try.

If anyone knows a good material and source to buy it, I'd love to hear it! Thanks in advanced!

Not sure if this would help, but we bought piezo actuators from http://www.faceinternational.com/. If they don't have anything that may help you, they might be able to recommend another source.
 
Goodfellow will sell you polyvinylidene fluoride (PVDF) which is a very thin piezoelectric film. You can cut small disks with a hole punch, place it in a similar hole in an insulating material and use small strips of conductive copper tape on either side of the disk to form a simple sensor or generator. When you apply a dynamic stress to the sensor, you'll generate a charge between the two ends of the circuit.

If you want a bit more information let me know and I can send you a paper describing it, or more usefully I can draw you a diagram of how I made mine.
 
could this PVDF film be of the order of 100µm thin? is it easily bondable with glass?
 
I used metallised 25 µm biaxial sheet. I don't know about bonding with glass, never tried. I used Mylar PET sheet of the same thickness as an insulating and protective substrate. That way I ended up with a very thin, flexible load cell.
 
@timmay...can u pls send me the exact schematic daig. showing the process of ur piezo electric strip...and i would be gratefull if u would let me know wer did u buy those...plsssss...and if possible pls do mail it to me @ 94yashwanth@gmail.com
 
@timmay...Could you please send me a paper describing your setup to csr_groups@yahoo.com? I was working on a design to generate electricity and wanted to try this method as well.

Regards,
CSR
 
Also @ timmay Hi, I'm also interested in your paper, perhaps it's also possible to send it to me: jurnhaeghebaert@msn.com . I'm working on a new way to count pedestrians with piezomaterial and I'm looking to make it generate it's own electricity, so this method could be usefull to me to.
