Proc. ASME. IDETC-CIE2024, Volume 11: 36th Conference on Mechanical Vibration and Sound (VIB), V011T11A015, August 25–28, 2024
Publisher: American Society of Mechanical Engineers
Paper No: DETC2024-142678
... the ball to roll back and forth, magnetically plucking a cantilever beam that is fixed underneath it and carrying a tip magnet. Frequency up-conversion is achieved as the beam vibrates at its natural frequency, which is higher than the excitation frequency, and this is employed to harvest energy...

Proc. ASME. IDETC-CIE2020, Volume 7: 32nd Conference on Mechanical Vibration and Noise (VIB), V007T07A009, August 17–19, 2020
Publisher: American Society of Mechanical Engineers
Paper No: DETC2020-22561
... Abstract In this study, an impact based frequency up-conversion mechanism is studied using discontinuous dynamics theory. The mechanism consists of a sinusoidal vibrating plastic beam as a driving element and a piezoelectric bimorph as a generator. In order to remove the unfavorable stick...

Publisher: American Society of Mechanical Engineers
Paper No: DETC2019-97883
... Abstract This study investigates an impact based frequency up-conversion mechanism via discontinuous dynamics analysis. The mechanism composed of a stopper and a piezoelectric bimorph. The piezoelectric beam is subjected to a sinusoidal base excitation and impacts with the stopper...
