Piezoelectric strips?

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.

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.
