The application of a silk strain gauge in pig skin (abdomen perpendicular to spine) tensile tests. (a) Snapshots taken during the uniaxial tensile test on pig skin. The silk strain gauge was attached on the surface of pig skin. (c) Strain vs time curves obtained from the Instron monitoring and FFT analysis. (c) Stress-strain curves obtained from the Instron monitoring and FFT analysis (d) Poisson's ratio vs strain curves calculated from FFT analysis.
