Also, it can be flexed so the evaluation of the bending characteristic by a bending test was carried out. The bending test equipment was manufactured in order to carry out the test. As the result of the bending test, it was found that the relation between the voltage output of the sensor and an angle of the test piece is linear. Also, the bending characteristic under various conditions of gauge length, width, thickness, and structure of silicon rubber were investigated. Additionally, the bending simulation of the laminated rubber sensor by FEM was performed in order to consider new structures or materials. The boundary condition for the bending simulation and evaluation method has been proposed. The result of the bending simulation was in good agreement with the experiment by using the proposed equation. Moreover, the characteristic of the multistage bending was evaluated experimentally and analytically, and the result according to the theory was obtained.
