| Abstract: | By analyzing the significance of small-strain testing,we get its value and prospect in the practical applications.In this paper,based on analysis of the conduction mechanism of carbon nanotube and the preparation of thin-film resistors,we made use of the characteristics that its resistance changes more sensitively with the deformation,converted the resistance signal into the voltage variation.We finished this sensorm with the data collection,amplification and digital processing. |
