[misc.wanted] Piezoelectric sheeting?

ch@well.UUCP (03/07/87)

	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

What you want is poly-vynilideine fluoride film (spelling not guaranteed), 
commonly called PVDF. 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.
