|Keywords:||MECHANICAL INDUSTRIAL ENGINEERING;DYNAMIC ANALYSIS;SINGLE WALL CARBON NANOTUBES;BIO-SENSORS|
|Abstract:||Since the discovery of carbon nanotubes (CNT) it has been the subject of extensive research. Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively. The strength and flexibility of carbon nanotubes makes them of potential use in controlling other nanoscale structures that is why they play an important role in nanotechnology engineering. Carbon nanotubes have been used as potential application component as resonators, mass sensors and structural element in mechanical field. It can also be used as a biosensor for the treatment of many dangerous diseases in biomedical field. Some of these applications require high amount of precision in measurement and CNT to be faultless. In this report, vibration analysis of CNT based biosensor is discussed in detail. Modal analysis of carbon nanotube as biosensors is done in two different configurations. The extent of this report is limited to the analytical and numerical analysis SWCNT as a biosensor has been illustrated. CNT is modeled using finite element method by taking molecular mechanics approach. In case of CNT application as a structural element, effect of tensile, bending and torsional loading on nanotube aspect ratio for different diameters of armchair and zigzag CNT is discussed for three different boundary conditions. Non linear vibration of CNT based biosensor is also discussed in detail. Outcome of this report helps us to predict the change in properties of CNT like resonant frequency due to various parameters and how it affect the vibrational behavior. Simulation results can also be used to predict the behavior of CNT in non linear regime.|
