An ultra-sensitive mode-localized accelerometer is reported in this letter. In order to lower the coupling factor of the coupled resonators thus improving the parametric amplitude ratio sensitivity, a stiff anchor support is employed as a mechanical

This paper reports a precision mode-localized accelerometer operating in a higher-order flexural mode. The accelerometer consists of two symmetric resonators coupled by a central rigid coupler to generate an ultra-weak coupling factor. A reduced nois

The amplitude ratio output metric in mode localized weakly coupled resonators has been established to show superior rejection of first order temperature and pressure variations over frequency shift output metric. This work for the first time document
Bulk acoustic wave gyroscopes have been researched for potential benefits such as immunity to shock and vibration and the high Q factors achievable with the bulk modes. This paper outlines an approach to address mode matching in bulk acoustic wave (B

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, for the first time, reports on a transducer configuration employing weakly coupled resonators demonstrating significant modal overlap. Existing multimode/mode-localized sensors conventionally operate in a regime where modal overlap is neg
