1. A capacitive strain sensor configured to measure a strain, the sensor comprising:
a dielectric layer;
a first electrode placed on a first face of the dielectric layer; and
a second electrode placed on a second face of the dielectric layer,
wherein the first electrode is formed of a single-walled carbon nanotube paper, and
wherein the single-walled carbon nanotube paper has plural pre-cracks made according to a pattern and a depth of the pre-cracks in the first electrode is smaller than a thickness of the first electrode.
