Abstract
An autonomous sensor that 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 produces mechanical energy. The proof mass is attached to the snap-through buckling beam. The proof mass transfers mechanical energy to two piezoelectric transducers that convert the mechanical energy into electrical energy and produce an output signal. The ultra-low-power microcontroller unit converts the output signal into output data. The wireless transmitter transfers the output data to an external device. The power management unit provides the electrical energy to the ultra-low-power microcontroller unit and the wireless transmitter. The power storage unit is rechargeable, stores electrical energy from the two piezoelectric transducers, and non-replaceable. The autonomous sensor simultaneously harvests energy and measures vibrations in an external environment.
