Mode-localized sensors have attracted great attention due to the high parametric sensitivity and common mode rejection to temperature drift. The reported results from such sensors has largely relied on operation in the linear regime. However, operati

This paper demonstrates a resonant accelerometer employing weakly coupled resonators for inertial force transduction. An ultra-low virtual mode coupling is established by employing the parametric pump in the coupled resonators to enhance the parametr
This paper builds on the recent demonstration of three-wave mixing based phononic frequency comb. Here, in this process, an intrinsic coupling between the drive and resonant frequency leads to a frequency comb of spacing corresponding to the separati
