摘要

This thesis presents a novel hybrid multimodal energy harvesting device consisting of an unbalanced rotary disk that supports two transduction methods, piezoelectric and electromagnetic. The device generates electrical energy from oscillatory motion either orthogonal or parallel to the rotary axis to power electronic devices. Analytical models of the device were developed, from which numerical simulations were performed for several different generator sizes. Two prototypes, 180 mm and 100 mm in diameter, respectively, were fabricated and characterized experimentally with a modal shaker. The 180 mm prototype generated 120 mW from the electromagnetic system at 5 Hz and 0.8g, and 4.23 mW from the piezoelectric system at 20.2 Hz and 0.4g excitation acceleration. Finally, the power generation capabilities of the two prototypes were compared to other similar devices.
