Abstract
Dr. Daqaq’s research focuses on the application of various nonlinear
phenomena to improve the performance of micro-power generation
systems, micro-electromechanical systems, and vibration assisted
manufacturing processes. Dr. Daqaq’s research is funded through several
grants from the National Science Foundation including the prestigious
2010 CAREER award. His research has also been recognized at the
national level through several awards including the 2016 ASME C. D. Mote
Jr. Early Career Award, the 2014 ASME Gary Anderson Early Achievement
Award, the 2014 Eastman Chemical Award for research excellence, and
the 2012 Clemson University Board of Trustees Award for Faculty
Excellence. He currently serves as an Associate Editor for the ASME
Journal of Vibration and Acoustics and as a Subject Editor for the Journal
of Nonlinear Dynamics.

Vibratory energy harvesters typically exploit ordinary direct resonances to
mechanically amplify environmental inputs before channeling a portion of
their energy into an electric load using an electromechanical transduction
mechanism. Nonetheless, parametric resonance which has also been
recently exploited, but to a lesser extent, holds a key advantage over
direct excitations in that, when the level of input excitation exceeds a
certain threshold, the amplitude of growth associated with parametric
pumping is not limited by the total linear damping present in the system.
While all of the previous research studies using parametric resonances for
energy harvesting focused on utilizing it as a means of mechanical
amplification, this letter demonstrates that vibratory excitations can also
be used effectively to induce parametric resonances in the harvesting
circuit itself, thereby providing a direct and simple means of electric
amplification. A vibratory energy harvester exploiting this phenomenon is
proposed in this letter and is shown to produce a maximum of 18 mW
root-mean-square power per 1 g of input acceleration.
