Abstract

We find that intrinsic localized modes (ILMs) in microelectromechanical cantilever arrays can be induced by the spatiotemporal chaos dynamics. For typical settings, spatiotemporal chaos is ubiquitous and can act as a natural platform for ILMs to arise. Our study suggests an experimental approach to preventing ILMs, i.e., to choose the modulation frequency so as to place the system in a regime where there is a low energy stable state.
