In ordinary consciousness, noise is associated with the term “hindrance”; it is considered as a nuisance that can lead to communication or signal transmission failure or prevent the detection of a weak signal to be measured. However, intensive investigations, performed in the last decades, have shown that under certain conditions the impact of noise can be counter-intuitively a resource. In nonlinear systems, noise can induce novel regimes leading to the formation of synchronized structures, coherence between the output and the input of resonators or even to the amplification of weak signals. In other words, noise can play a constructive role, with potential benefits for signal processing or measurement for instance.

We aim at enlarging the scope and potential use of such noise-aided processes with strong impact in noise-assisted applications including signal processing or sensing. It will extend their field of application by harnessing noise induced phenomena in novel playground formed by single and coupled Nano-Opto-ElectroMechanical resonators
