ABSTRACT
This research work explores the mechanical properties and piezoresistive behavior of carbon nanotubes (CNTs) with a focus on their chiral indices (n, m). It presents a comprehensive investigation into the bending rigidity of CNTs using classical plate theory and establishes a theoretical framework to predict their strain sensitivity. Additionally, the crucial parameter of gauge factor, essential for assessing piezoresistivity, is calculated. This work also provides a comprehensive understanding of CNTs' mechanical and piezoresistive properties, paving the way for their application in energy harvesting. The findings offer valuable insights into harnessing mechanical strain and converting it into usable electrical energy, with a focus on achieving higher gauge factors for enhanced performance in energy harvesting devices.
