Abstract: A piezoelectric composite material is formed from a cellulosic material and an inorganic piezoelectric material dispersed in a piezoelectric polymer. The piezoelectric polymer of the composite material has a dielectric constant of from 10 or more. A method of making a piezoelectric is also disclosed wherein a matrix of a cellulosic material, an inorganic piezoelectric material, and a piezoelectric polymer material is formed. The matrix is formed into a piezoelectric composite body.
