A special bidirectional force measuring sensor is designed for the experimentation of bionic adhesive material.The elastic body is weaken locally according to the principle of stress concentration

the parameters of the elastic body is gained by using the theory of material mechanics and the FEM program ANSYS

the best location to stick the strain gauge is found with the technique of mapping results onto a path which provided by ANSYS.Through calihrating the sensor

its static performance is got.Its measurement range for vertical force is 3.0 N with 0.008 N distinguishability and measurement range for horizontal force is 3.5 N with 0.01 N distinguishability.
