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.
