Nonlinear Dynamic Response of Nanocomposite Microbeams Array for Multiple Mass Sensing

Nanomaterials, 2023
A nonlinear MEMS multimass sensor is numerically investigated, designed as a single input-single output (SISO) system consisting of an array of nonlinear microcantilevers clamped to a shuttle mass which, in turn, is constrained by a linear spring and a ...
