Abstract: In an embodiment, provided are nanoresonators, nanoresonator components and related methods using the nanoresonators to measure parameters of interest. In an aspect, provided is a nanoresonator component comprising an elongated nanostructure having a central portion, a first end, and a second end and an electrode having a protrusion ending in a tip that is positioned adjacent to the elongated nanostructure. The electrode is used to impart a highly-localized driving force in a perpendicular direction to the nanostructure to induce geometric non-linear deformation, thereby generating non-linear resonance having a broadband resonance range that spans a frequency range of at least one times the elongated nanostructure natural resonance frequency.

Abstract: A nonlinear attachment induces energy to be transferred and/or to be pumped from a primary system or primary structure to the nonlinear attachment. The nonlinear attachment is an essentially nonlinear device and functions as a nonlinear energy sink. The nonlinear attachment attaches to the primary system or primary structure as a module and does not require connection to a ground. The energy is irreversibly pumped from the primary system or primary structure to the nonlinear attachment during transient resonance capture between the nonlinear attachment and the primary system or primary structure. The nonlinear attachment attenuates the energy of the primary system or primary structure. The nonlinear attachment locally confines the energy and/or dissipates the energy through a passive means and/or an active means.
