Scheme for Mechanical Measuring Device Used to the Compression Elasticity of Soft Tissue

It's hard to measure the elastic modulus of the soft tissue accurately. Because the stretched length of the soft tissue is difficult to obtain. For tensile stress, the fixture of soft tissue is a problem, and cutting size of soft tissue is inexact. In the paper, the soft tissue is cut by the various molds. The stepper motor is used to drive the eccentric wheel, which compress the tissue. Using the distance sensor records the compressed size and using pressure sensor records the forces. Then the computer collects and stores the data and then calculates the elasticity parameter of the tissue. This paper focuses on the accurate obtaining deformation as well as stress.
