In recent years, great attention has been paid to the energy harvester from the almost ubiquitous ambient energy to the electronic energy colocated with microdevices. An effectively nonlinear energy harvesting stochastic systems have been investigated, and effects an ubiquitous ambient stochastic force and system parameters on the system output are discussed by both theory and experiment. In the nature world, many realistic inanimate and animate systems possessing self-regulation control mechanisms by feed back loops, the transmission of from the input signal to the output signal need to take some time, implying that the time delay phenomenon occurs and it is a ubiquitous universal phenomenon. What's more significant is that in the realistic stochastic system effects of the time delay are more interesting and important. A series interesting results of effects of the time delay are found.

In my paper, we study stochastically forced limit cycles of the energy harvesting system subjected to the time delay and find supersensitive limit cycles of the energy harvesting stochastic system. We show effects of the time delay on probability distribution of the energy harvesting stochastic system. By investigating the characteristic correlation time of the system, we point out coherence resonance and anti-coherence resonance phenomena induced by the time delay and effects of the parameters on the stability and the output of the system. simple guidelines.
