Abstract
The composite material is obtained by coating a fabric with a polymer. Coating is performed either in the cold state by dipping the fabric in a solution of polymer dissolved in a solvent or in the hot state by dipping in a molten polymer. The film of composite material thus obtained is then endowed with piezoelectric properties by subjecting it to an intense electric field.
