<p>1. Process for the production of a piezoelectric composite material from pyroelectric grains according to which : - pyroelectric grains (8) having a zero resultant dipole moment, are placed in a liquid material (4), - an electric field is applied to the thus-obtained liquid suspension, and - the suspension obtained is solidified, said process being characterized in that, before solidification, a transistory dipole moment is produced on each pyroelectric grain to orient said transitory dipole moments in a single direction, the grains being non-ferroelectric.</p> |
