Inducing intrinsic localized modes in microelectromechanical cantilever arrays by frequency modulation

We articulate a control method to induce intrinsic localized modes at programable bielement cell in driven microcantilever arrays. The idea is to excite a preassigned cantilever to an oscillating state with significantly higher amplitude than the average by using feedback signal to modulate the frequency that drives the whole array. Our control method is thus global, which is advantageous in microsystems as local pinning actuation may be difficult to implement at small scales. (C) 2009 American Institute of Physics.
