First Claim
1. A transducer device of fluid-dynamic energy into electrical energy, usable as flow meter or as an energy harvester, comprising:
- a mechanical element interacting with a flowing fluid, supported to at least oscillate in a plane with a component parallel to flow direction and another component transverse or orthogonal to a surface transversal to the flow direction and belonging to the mechanical element, wherein the mechanical element is brought into oscillation or vibration by the fluid flow, by way of one or more elastic suspending elements;

Abstract
A device transducing fluid dynamic energy into electrical energy, usable as a flow meter or energy harvester, includes a mechanical interaction element with a fluid flow, which is brought into oscillation or vibration by the fluid flow, by way of one or more elastic suspension elements; a magnetic induction electromotive force generator, dynamically connected to the mechanical interaction element by the fluid flow, which crosses an electric conductor, moved in the magnetic field by the oscillating or vibrating motion of the mechanical interaction element, thus generating an induced current in the conductor; and a collection unit for the electrical signal generated by induction. The mechanical interaction element is suspended to oscillate around an axis transversal to the flow direction and corresponding to a transversal axis half way along the mechanical interaction element.
