GENERATEUR D'ELECTRICITE FONCTIONNANT PAR RECUPERATION D'ENERGIE

The invention relates to a generator (100) for transforming a rotational motion of a rotary member (30) on a main axis into an accumulation of electric charge at the terminals of two electrodes, comprising: * a support (1); * an electroactive transducer (10) positioned in a plane that is perpendicul...

More Information
Summary:The invention relates to a generator (100) for transforming a rotational motion of a rotary member (30) on a main axis into an accumulation of electric charge at the terminals of two electrodes, comprising: * a support (1); * an electroactive transducer (10) positioned in a plane that is perpendicular to the main axis and composed of a layer of piezoelectric material and of the two electrodes; at least one first portion of the transducer (10) being attached to the support (1); * an actuator body (20), rigidly connected to a second portion of the transducer (10) so as to apply a stress to this transducer when the actuator body (20) is moved on the main axis, and including at least one first magnetic element (21); * the rotary member (30) including at least one second magnetic element (31) configured to generate a magnetic field gradient in the vicinity of the first magnetic element (21); the rotational motion of the rotary member (30) with respect to the support (1) causing said magnetic field gradient to vary so as to induce bidirectional or unidirectional magnetic forces on the first magnetic element (31) along the main axis, and thus to move the actuator body (20) along the main axis.
