Abstract:

To efficiently scavenge the energy from low-frequency ambient vibrations, this paper proposed a piezoelectric energy harvester (PEH) with a six-segment folded trapezoidal beam. The new configuration provides the PEH with a lower natural resonant frequency and closer resonance peaks, which makes the harvester suitable to daily vibrations w...More
