Abstract
This paper discusses non-contact stiffness sensing of elastic tissue with coupling effect by using only displacement measurement during a force impartment. Supposing that both applied force and the point displacement of tissue are known, we can obtain stiffness parameters of living tissue by utilizing a single layered model with horizontal and vertical stiffness units. From both analysis and simulation, we confirm that the parameters are nicely estimated under the condition of at least two different sets of the force and the displacement with appropriately selected initial condition.
