Active sensing for viscoelastic tissue with coupling effect

This paper discusses active sensing for detecting viscoelastic parameters of living tissues with the coupling effect among neighbors. Supposing that both applied force and surface deformation of tissue are known with respect to time, we obtain viscoelastic parameters of living tissue by utilizing a single layered model with horizontal and vertical units where each unit is composed of both stiffness and damping elements. We show that the model with only appropriate number of units can nicely express the dynamic characteristic of human skin.
