Nonlinear Energy Harvesting With Tools From Machine Learning
<p>Energy harvesting is a process where self-powered electronic devices scavenge ambient energy and convert it to electrical power. Traditional linear energy harvesters which operate based on linear resonance work well only when excitation frequency is close to its natural frequency. While various …

Micro-Scale and Nonlinear Vibrational Energy Harvesting
This work addresses issues in energy harvesting that have plagued the potential use of harvesting through the piezoelectric effect at the MEMS scale. Effective energy harvesting devices typically consist of a cantilever beam substrate coated with a thin layer of piezoceramic material and fixed with …

Random perturbations of delay differential equations at the verge of instability and periodically driven nonlinear oscillators
… a linear DDE perturbed by small noise and small nonlinearities. The instability scenario considered is the following: a pair of roots of the characteristic equation (critical eigenvalues) lie on the imaginary axis of the complex plane, and all other roots have negative real parts (stable …

Nonlinear Dynamics of Energy Harvesting Ocean Buoys
… different ways that the performance of ocean energy harvesting buoys can be improved by intentionally inserting nonlinearities into the system. The goal is to maximize the amount of energy that is extracted from ocean waves across a broad range of environmental conditions. First, the …
