The authors would like to thank Professor Brian Mann for taking the time to read this paper and provide his insightful perspective into the role of nonlinearities in energy harvesting. Professor Mann has significant expertise in the field of energy harvesting and his commentary identifies several of the key advantages that result from the deliberate introduction of nonlinearities into energy harvesting devices. The goal of this closure is to complement his commentary by sharing additional thoughts that could be beneficial for the energy harvesting research community.
To begin, we would like to point out that the complexity of the response behavior of nonlinear harvesters as compared to their linear counterparts remains the biggest challenge preventing us from optimizing their performance and fully reaping their potential benefits. Nonlinear harvesters exhibit different behaviors that are not seen in linear systems including sub-harmonic, super-harmonic, quasi-periodic, aperiodic and chaotic responses. The long time response...
