Carbon Nanotubes (CNTs) have impressive electrical, electromechanical and mechanical properties, these properties promoted to a lot of applications. The composites of CNT with polymers have potential applications in strain sensors. The paper discusses the preparation of CNT film by using Vacuum filtration method and preparation of composite by Sandwich method which is used to fabricate the sensor structures using CNT and PDMS films. Bending test was performed with CNT-PDMS based sensors, which are bonded on Aluminum plate. These studies demonstrated the effect of aspect ratio on sensitivity of CNT-PDMS sensor and Simulation was performed using COMSOL Multiphysics 5.3a software. It was found that CNT-PDMS strain sensor shows linear relationship between change in resistance and applied strain. The gauge factor and initial resistance of sensor increases as the CNT film aspect ratio increases.
