Composite piezoelectric material and its fabrication process

Creators

Description

Composite piezoelectric material, of plastic or ceramic, characterized by the fact that it contains pyroelectric grains, not ferroelectric, embedded in a matrix, of which all the polar axes are oriented parallel to a given direction. Application in the field of ultrasonics, used in particular for surface cleaning, weld inspection, and medical echometry
