Abstract : We review the experimental role NanoElectroMechanical System (NEMS) networks play vis a vis the MURIs scientific and validation goals which target new theoretical understanding of the dynamics of large-scale interconnected networks and their control. Our plans for NEMS networks are substantially updated based on our theoretical and experimental results during the MURIs first two years, providing a clear roadmap for the coming years that discusses relative benefits and costs. For example, we briefly compare how NEMS networks compare to alternative, potential validation platforms, including one based on Field-Programmable Gate Arrays (FPGAs). We also provide a relatively detailed outline of system-on-chip implementation of large-scale NEMS networks that will allow us to explore the nonlinear dynamics, statistical mechanics, and control of very large oscillator networks.
