Abstract The performance of a ring of linearly coupled, monostable nonlinear oscillators is optimized towards its goal of acting as energy harvester – through piezoelectric transduction – of mesoscopic fluctuations, which are modeled as Ornstein-Uhlenbeck noises. For a single oscillator, the maximum output voltage and overall efficiency are attained for a soft piecewise-linear potential (providing a weak attractive constant force) but they are still fairly large for a harmonic potential.

Treating the signal-to-noise ratio (SNR) as the signal quality index, the stochastic resonance (SR) phenomenon in a coupled monostable system (CMS) is investigated and the SR induced by the CMS is greater than that for a monostables system.
