Measuring and Modelling Nonlinear Elasticity of Ex Vivo Mouse Muscles

Figure 1

Example of images of a TA muscle acquired by the optical system. The indentor and the lever arm of the actuator/transducer were also captured. (a) Precompression image: h is the length of the circular piston. (b) Image acquired after a preload of 8 mN was applied: is the initial length of the sample in the cross-fiber direction.
