The Origin of Mass-change Sensitivity within Multi-layered, Non-uniform, Piezoelectrically-actuated Millimeter-sized Cantilever (PEMC) Biosensors: Vibrational Analysis through Experiment and Finite Element Modeling (FEM)

B.N. Johnson[1], and R. Mutharasan[1]

[1]Department of Chemical and Biological Engineering, Drexel University, Philadelphia, Pennsylvania, USA

A 3D finite element model (FEM) of the PEMC sensor was developed to characterize the modes of vibration that have demonstrated high sensitivity to mass-change in experimentally fabricated sensors. The fundamental bending mode of vibration and the 1st bending harmonic are predicted at 10 ... En savoir plus
