Towards an Ultra Sensitive Hybrid Mass Sensor Based on Mode Localization without Resonance Tracking

We present a mode localized mass sensor prototype based on a hybrid system excited at a fixed frequency slightly below the resonances. Indeed, we show, both theoretically and experimentally, that this condition yields higher sensitivities and similar sensitivity ranges than that of resonance peak tr...
