High-Resolution Strain Measurement for Biomechanical Parameters Assessment in Native and Decellularized Porcine Vessels

Figure 6

Four different frames from a recording of a uniaxial tensile test in a decellularized vessel with an increasing load. The sample is stretched in the direction marked with red arrows, and the strain tracking is enhanced thanks to the speckle pattern applied to the sample.

(a) Load = 44.748 g

(b) Load = 180.510 g

(c) Load = 260.370 g

(d) Load = 340.235 g
