In this paper, we treat the harvester as a nonlinear forced oscillator and bound the area of control parameters where the system displays regular harmonic oscillations allowing the conditioning circuit to operate in the most effective mode. Before the system exhibits irregular behaviour, there exists a universal optimal value of normalised converted power regardless of the system design and control parameters.||Funding Details:||Science Foundation Ireland||Type of material:||Journal Article||Publisher:||American Institute of Physics||Journal:||Applied Physics Letters||Volume:||101||Issue:||17||Start page:||173904-1||End page:||73904-4||Copyright (published version):||2012 American Institute of Physics||Keywords:||Vibration energy harvesting; Electrostatics; Energy harvesting; Oscillations; Oscillators; Vibrations||DOI:||10.1063/1.4764009||Language:||en||Status of Item:||Peer reviewed|
