Introduction

Vincenzo Marletta is a distinguished inventor based in Catania, Italy. He has made significant contributions to the field of autonomous sensor technology, holding 2 patents that showcase his innovative approach to energy harvesting and vibration measurement.

Latest Patents

One of his latest patents is an **Autonomous Sensor**. This device includes a snap-through buckling beam, a proof mass, an ultra-low-power microcontroller unit, a wireless transmitter, a power management unit, and a power storage unit. The snap-through buckling beam generates mechanical energy, while the proof mass is attached to it, transferring energy to two piezoelectric transducers. These transducers convert mechanical energy into electrical energy, producing an output signal. The ultra-low-power microcontroller unit processes this signal into output data, which is then transmitted wirelessly to an external device. The power management unit supplies electrical energy to the microcontroller and transmitter, while the rechargeable power storage unit stores energy from the piezoelectric transducers. This autonomous sensor is capable of simultaneously harvesting energy and measuring vibrations in its environment.

Another notable patent is the **Non-linear Bi-stable Buckled Beam Energy Harvester Using Repulsive Magnetic Force for Asymmetry Compensation**. This system features a flexible beam secured between two supports, which are spaced closely enough to cause the beam to buckle. The beam switches between two positions in response to external vibrations. A magnetic proof mass is coupled to the beam's midpoint, and at least one permanent magnet is positioned nearby to exert a repulsive force on the proof mass. Piezoelectric transducers are strategically placed to harvest energy from the beam's movements.
