Abstract
L'invention concerne la polarisation des membranes capables de former des matières piézoélectriques. Elle se rapporte à un procédé qui comprend la formation d'un empilement de membranes, avant application de la tension de polarisation, cet empilement permettant l'augmentation de la tension appliquée et la suppression des claquages. Application à la préparation d'électrets.
