Piezoelectric Materials

[simisastry]

Could some one help me trace a flexible Piezo Electric film manufacturer. I need a film that could be integrated into a Textile substrate for sensor purposes. I do not need a ceramic based piezo material but something akin PVDF Piezo film.

Advanced Cerametrics in Lambertville, NJ makes PZ fibers that are used in composites - is this what you are looking for?

Thanks SMF1964. I am not looking for composities but a thin film of thickness of around 1mm. A film that could be integrated between 2 layers of clothing.

I have seen a kids lab where you use a trash bag and make a piezo sensor out of it. As I recall you strain it a certian amount at a specific temp. I don't recal if you chemicaly treat it before or after.
And I can't find a damn link to the process.
The US Navy was doing the development. The idea was to coat submarine hulls with piezo material. It could be used both as sensors and as an active noise suppresion system.

Corrosion never sleeps, but it can be managed.

The Navy was probably going to use the material to detect undersea mountains.

Nothing obvious, but you might have to discuss this with a supplier:
