Title (EN) AN ELECTROMECHANICAL GENERATOR FOR CONVERTING MECHANICAL VIBRATIONAL ENERGY INTO ELECTRICAL ENERGY
(FR) GENERATEUR ELECTROMECANIQUE DESTINE A TRANSFORMER UNE ENERGIE VIBRATIONNELLE MECANIQUE EN ENERGIE ELECTRIQUE
Abstract: front page image
(EN)An electromechanical generator for converting mechanical vibrational energy into electrical energy, the electromechanical generator including a cantilever spring having a fixed end, a free end and a central portion therebetween, a mount for the cantilever spring to which the fixed end is fixed, a mass located at the free end of the cantilever spring, the mass including either a coil or at least one magnet defining a region of magnetic flux, wherein at least one of the fixed end and the free end of the cantilever spring is substantially stiffer than the central portion of the cantilever spring.
(FR)L'invention concerne un générateur électromécanique destiné à transformer une énergie vibrationnelle mécanique en énergie électrique. Le générateur électromécanique comprend: un ressort cantilever semi-elliptique présentant une extrémité fixe, une extrémité libre et, entre les deux, une partie centrale; un support pour le ressort cantilever auquel est fixée l'extrémité fixe; une masse située à l'extrémité libre du ressort cantilever et comprenant soit une bobine, soit au moins un aimant délimitant une zone de flux magnétique. Au moins l'extrémité fixe ou l'extrémité libre du ressort cantilever est sensiblement plus rigide que la partie centrale du ressort cantilever.
