In order to make our models as life-like as possible, we use various mechanical testing techniques to determine the mechanical properties of both porcine and cadaveric tissues from the respective organ of interest. The tests include but are not limited to tensile stress vs strain, perfusion forces, and compression forces. Using this data, we can then modify our hydrogel material to match the properties of the respective tissue. We then re-test our own synthetic tissue and as a result, we are comparing the mechanical properties of real tissues to our hydrogel to ensure life-like procedures for surgeons.
