The mechanical properties of stacked graphene sheets with varying number of layers are examined. The stacked sheets are assembled by manually combining single layer CVD-grown graphene monolayers, resulting in a turbostratic multilayer graphene with irregular layer spacing greater than crystalline graphite. Due to the presence of multiple layers, the material is analyzed as a plate rather than a membrane...
In this paper we design a novel piezoelectric MEMS biosensor for the detection of hepatitis virus. A PZT-5A piezoelectric based poly-silicon cantilever of length 500 µm × 100 µm × 7 µm is used in the model which is actuated by electromagnetic induction for sensing changes in mechanical vibrations caused by adsorption of virus of the order of pg of sample mass at the tip of cantilever, producing an...
