ABSTRACT:
A piezoelectric composite material having increased sensitivity and stability with time is described. The composite includes a volume fraction of from 20 to 60 percent of piezoelectric crystals having a size distribution of from 1 to 300 microns dispersed in a polymer matrix. The composite matrix is characterized by a shear modulus of at least 50 psi.
