A New Theoretical Model of a Carbon Nanotube Strain Sensor

Qiu, Wei; Kang, Yi Lan; Lei, Zhenkun; Qin, Qing Hua; LI, Qui


Carbon nanotubes (CNTs) are potential strain sensors due to their excellent mechanical and spectral properties. A new theoretical model of a CNT strain sensor is obtained by applying the polarized Raman properties of CNTs, which calculates the synthetic contributions of Raman spectra from the CNTs in random directions. By using this theoretical model, the analytic relationship between planar strain components and the Raman shift increment of uniformly dispersed CNTs is obtained, which is...[Show more]
