Hydrostatic pressure properties of piezoelectric flexible composites are reported as a function of PbTiO
3
volume fraction and particle size. These composites, typically referred to as Piezo-Rubber, consist of PbTiO
3
and a polymer and were developed at NTK-NGK.
There is a hydrostatic pressure independence region and a hydrostatic pressure dependence region in terms of PbTiO
3
volume fraction and its average particle size. The hydrostatic pressure dependence region can be further separated into a linear correlational region and a non-correlational one.
