Kauth, ChristianPastre, MarcKayal, Maher2015-02-202015-02-202015-02-20201410.1109/Jsen.2014.2322084https://infoscience.epfl.ch/handle/20.500.14299/111573WOS:000347318000001Mass sensing has so far rather developed along the resolution axis, reaching atomic-scale detection, than into the direction of high speed. This letter reports on a novel self-calibrating technique that makes high-speed inertial mass sensors capable of instant high-resolution detection and weighing. The sensing nanoelectromechanical resonator is embedded into a phase-locked loop and the sensor-inherent nonlinear phase-frequency relation is exploited for autocalibration.Nanoelectromechanical systemsnonlinear systemsphase locked loopssystem analysis and designtext::journal::journal article::research article
