Strain Components

A strain sensor composed of carbon nanotubes with Raman spectroscopy can achieve measurement of the three in-plane strain components in microscale. Based on previous work on the mathematic model of carbon nanotube strain sensors, this paper presents a detailed study on the optimization, diversification, and standardization of a CNT strain sensor from the viewpoint of metrology. A new miniaccessory for polarization control is designed, and two different preparing methods for CNT films as sensing media are introduced to provide diversified choices for applications. Then, the standard procedure of creating CNT strain sensors is proposed. Application experiments confirmed the effectiveness of the above improvement, which is helpful in developing this method for convenient metrology.

This paper introduceda study for the methodology of carbon nanotube (CNT) sensor applicable for the strain measurement in microscale. By using the Raman strain sensitive and polarization selectivity of the carbon nanotubes, the analytical relationship of carbon nanotube strain sensor for each polarization Raman configuration are deduced and compared. The work regarded that the dual coordination polarization-controlled configuration is most suitable for the in-plane strain measurement. Then, a new method for this configuration is presented. Experiments proved that the proposed method can effectively realize the measurement of in-plane strain components by using polarized Raman.
