In recent years, energy harvesters using pendulum systems have often been applied in ultra-
low-frequency environments, such as ocean waves, human motion, and structural vibration …

Piezoelectric energy harvesters tend to convert energy from ambient vibration to electricity,
which can gain a higher output voltage at resonance region. How to obtain a larger working …

Prior research has investigated resonators capable of self-tuning through the use of a sliding
mass. This passive tuning mechanism can be utilized to improve vibration control; however …
