Three-axis inertial sensing based on a valley topological phononic metamaterial

Xianze Zheng, Jian Xun Zhao, Najib Kacem, Zeyuan Dong et autres

We propose an electrostatically coupled valley phononic metamaterial for three-axis inertial sensing (two accelerations, one rotation), which consists of unequal masses on the lattice sites to break the inversion symmetry. Different combination constructions of the metamaterials can form three types of interfaces …

Electrostatically coupled tunable topological phononic metamaterials for angular velocity sensing

Jian Xun Zhao, Xianze Zheng, Najib Kacem, Zeyuan Dong et autres

We propose an electrostatically coupled phononic metamaterial for angular velocity sensing, whose sensitivity is immune to external damping and local material defects; furthermore, the coupling strength and frequency range of bands are tunable by the voltages applied to the lattices. The induced …

A Parametrically Excited Mode-Localized Acceleration Threshold Sensor Using Supercritical Hopf Bifurcation

Yinghai Tang, Jian Xun Zhao, Najib Kacem, Zeyuan Dong et autres

Abstract A parametrically excited mode-localized acceleration threshold sensor was designed by using the Supercritical Hopf (SCH) bifurcation with high robustness to the fluctuation of driving voltage and damping while maintaining high sensitivity. The multi-physical dynamic model is established considering both the mechanical …

Toward acceleration sensing based on topological gyroscopic metamaterials

Xianze Zheng, Jian Xun Zhao, Najib Kacem, Pengbo Liu

In this paper, the equation of motion of graphenelike topological gyroscopic metamaterials under acceleration is derived, and the influence of the external acceleration on the band structure is investigated. The calculated results of band structure under acceleration of $1g$ are in good …
