“…In [48] a STB configuration has been investigated for the case of a periodic acceleration applied along the vertical direction. In this case, the weight of the proof mass load introduces an asymmetry in the force required to switch the beam from the bottom stable state to the opposite position.…”

“…To restore the symmetry in its dynamic bistable behavior, a compensation strategy exploiting a magnetic repulsion mechanism together with a magnetic proof mass on the beam was proposed in [48]. A schematization of the STB harvester with the repulsive permanent magnet placed at the optimal distance L m = 29 mm from the upper state position of the beam is shown in Figure 2.…”

“…The position of the repulsive magnet has been experimentally fixed by measuring the repulsive magnetic force exerted by the magnet on the proof mass through a dedicated setup which exploits a load cell (Transducer Techniques GSO-10) and the dedicated conditioning electronic. The setup and the measurement methodology are discussed in [48].…”

Energy Harvesting strategies coupled with the improvement of electronics and the progressive reduction of power requirements have been widely recognized as fundamental to enable self-powered (or autonomous) devices. Among all the potential energy sources, kinetic energy stemming from mechanical vibrations has been particularly extensively investigated for EH purposes due to its characteristics of heterogeneity and ubiquity. To exploit such energy sources, a suitable coupling mechanism to convert vibrations into electric charge is required; it must take into account the wide frequency bandwidth of mechanical vibrations as encountered in everyday scenarios. This review offers an overview of linear vs. non-linear strategies for EH, with a specific focus on different approaches to implement efficient coupling mechanisms; the performances of the specific solutions covered in this work are discussed.

Piezoelectric Energy Harvesting Systems play a vital role in energizing microelectronic devices with the low-frequency operation. Here, a novel piezoelectric energy harvesting device has been developed for low power electronic devices. The developed Piezoelectric Energy Harvesting Systems consists of a cantilever with poles projecting outwards and the cantilevers one end is connected to the wind-catcher, and another end is connected to the torsional spring. The developed Piezoelectric Energy Harvesting Systems signifies its application in energizing microelectronic devices. The cantilever is placed inwards to the piezoelectric crystal stack. When the wind strikes, a vortex is created in the windcatcher, which oscillates the cantilever and generates stress in the piezoelectric crystal stack to develop electric energy. The output voltage obtained from the Piezoelectric Energy Harvesting Systems does not affect any input frequency of the piezoelectric crystal. The result obtained shows that the developed Piezoelectric Energy Harvesting Systems generates 120-200 eV with 2.9 × 10 16 -4.84 × 10 16 Hz frequency considering an elementary charge unit as 40 for a variable wind flow of 4-9 m/s. This research aims to develop an efficient wind-based Piezoelectric Energy Harvesting Systems for low powered microelectronic devices.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…Solutions exploiting a STB beam configuration have been recently presented by the authors [3,[5][6][7][8] and demonstrated to be capable of power a wireless transmitter [9]. In [10,11] a magnetic repulsion mechanism to compensate for the asymmetric behavior of the device, in the vertical direction, due to the effect of the proof mass load, has been presented.…”

In this paper the possibility to exploit advantageously the Stochastic Resonance phenomenon in a Nonlinear Energy Harvester to scavenge energy from wide band mechanical vibrations is experimentally demonstrated. The device is demonstrated to be capable of scavenging energy in case of a subthreshold sinusoidal vibration and a wideband noise (limited at 100 Hz) superimposed. The existence of an optimal value of the noise intensity maximizing the switching ratio of the bistable beam, then the performances, is experimentally demonstrated. The harvester is observed to generate power up to about 60 µW and 150 µW in case of a subthreshold sinusoidal input at 1 Hz and 3 Hz with a superimposed noise limited at 100 Hz.
