Abstract[English]
An improved electro-mechanical principle for converting electric power into mechanical action and vice versa is described using dielectrics with extreme relative permittivity. The non-magnetic devices are based on relative movement of dielectrics in the presence of electric fields. The energy-saving devices use high-performance dielectrics based on ferroelectric nematic liquid crystals. Linear and circular mechanical action is proposed involving electromechanical actuators, non-magnetic motors and related electrical generators.[French]
L'invention également un principe électro-mécanique amélioré pour convertir de l'énergie électrique en action mécanique et vice versa, à l'aide de diélectriques ayant une permittivité relative extrême. Les dispositifs non magnétiques sont basés sur le mouvement relatif de diélectriques en présence de champs électriques. Les dispositifs d'économie d'énergie utilisent des diélectriques à haute performance à base de cristaux liquides nématiques ferroélectriques. Une action mécanique linéaire et circulaire est proposée, impliquant des actionneurs électromécaniques, des moteurs non magnétiques et des générateurs électriques associés.
