[.] Hello, I am looking for a source of piezoelectric "sheets". I have heard that several companies make/sell it, but I can't seem to find any references. What this is is a sheet (ranging from small to several square feet) of thin, semi-flexible, piezoelectric material coated on both sides by thin electrodes. I believe that there is a company in the Silicon Valley area that sells the sheeting as well as a line of high-frequency speakers based on the material. Can anyone please help me find a source? Thanks in advance, Chris Hayes -- Chris Hayes UUCP: ucbvax!dual!well!ch OR : {hplabs, ptsfa, lll-lcc}!well!ch

One manufacturer is the Pennwalt Corporation, based in King Of Prussia, Pa. It comes in all kinds of thicknesses, and gives an electrical response to force and temperature changes.
