Development of Piezoelectric Harvesters with Integrated Trimming Devices [PDF]
Applied Sciences, 2018 Piezoelectric cantilever harvesters have a large power output at their natural frequency, but in some applications the frequency of ambient vibrations is different from the harvester’s frequency and/or ambient vibrations are periodic with some ...
