“…Due to excellent characteristics of ceramics in heat and corrosive resistances combined with the toughness of metals, and the material properties vary continuously from one surface to another, the inter-laminar stresses at the interface would vanish. Recently, FGMs have been applied in micro-and nano-scale devices and systems, such as thin films [3,4], atomic force micro-scopes (AFMS) [5,6], micro-and nano-electromechanical systems (MEMS and NEMS) [7][8][9], and bio-mass sensing applications [10].…”

“…Moreover, it was demonstrated that the microstructure, size, and surface texture (i.e. surface roughness, waviness, and altered layer) of these resonators influence their performance in different applications [4,9,10,15]. The operating principle of nanodevices depends on models to transfer a resonator's property change into a value of the measured physical quantity.…”

Magnetron sputtering is a perfect technique for processing nanomaterials for engineering and medical applications. A material can be processed with specific mechanical properties, microstructure, and surface texture by controlling the parameters of magnetron sputtering. Therefore, studies should be conducted on investigating the processing conditions on the performance of nanomaterials processed by magnetron sputtering.In this study, effects of the processing force on performance of micro/nano-resonators produced by magnetron sputtering are revealed. The processing force is defined as the ratio of the sputtering power-tothe substrates traveling velocity. By comparing the substrate's traveling velocity to the deposition rate of the sputtered particles, relations are derived for the thickness and surface texture evolutions with the processing force. The coefficients of these relations are experimentally determined for mechanical resonators made of FeNiCr alloy. Then, the variations of the natural frequencies of these resonators with the processing force of magnetron sputtering and the deposition rate of the sputtered particles are depicted.It is demonstrated that special considerations should be given for the effects of the processing conditions when design mechanical resonators produced by magnetron sputtering.

Recently, detecting biological particles by analyzing their mechanical properties has attracted increasing attention. To detect and identify different bioparticles and estimate their dimensions, a mechanical nanosensor is introduced in this paper. to attract particles, numerous parts of the substrate are coated with different chemicals as probe detectors or receptors. The principal of cell recognition in this sensor is based on applying an electrical excitation and measuring the maximum deflection of the actuated cantilever electrode. investigating the critical voltage that causes pull-in instability is also important in such highly-sensitive detectors. the governing equation of motion is derived from Hamilton's principle. A Galerkin approximation is applied to discretize the nonlinear equation, which is solved numerically. Accuracy of the proposed model is validated by comparison studies with available experimental and theoretical data. The coupled effects of geometrical and mechanical properties are included in this model and studied in detail. Moreover, system identification is carried out to distinguish bioparticles by a stability analysis. Due to the absence of a similar concept and device, this research is expected to advance the state-of-the-art biosystems in identifying particles.
