  • We describe a method for the detection of nanometer scale displacements of nanoelectromechanical resonators. We also present an analysis of the mechanical motion of these devices. We evaluate the effectiveness of the detection technique by detecting displacements from a series of nanomechanical doubly clamped beam resonators with decreasing dimensions.
