Abstract: A capacitive strain sensor configured to measure a strain includes a dielectric layer; a first electrode placed on a first face of the dielectric layer; and a second electrode placed on a second face, opposite to the first face, of the dielectric layer. The first electrode is formed of a single-walled carbon nanotube paper, and the single-walled carbon nanotube paper has plural pre-cracks made according to a pattern.

Abstract: A strain characterization system includes a strain sensor having first and second electrodes that sandwich a dielectric layer to form a capacitor; a power source configured to inject a signal VAC between the first and second electrodes of the strain sensor; and a controller configured to control the power source and to select a frequency of the power source. The controller is configured to select first to third different frequencies for determining a strain magnitude, a strain location, and an extent of a strain area.
