Human creats the numerous kinds of gesture of different emotion by the motion and straining of the facial skin including the facial wrinklings. Basically, the deformation of the facial skin is mainly occurred by the contraction of the facial muscles under the skin. Therefore, it is necessary to clarify the mechanism of skin deformation behaviors induced by these contractions of facial muscle under various emotions. The determination of constitutive parameters in constitutive equation for active and passive mechanical properties of facial muscle is indispensable based on the experimental results. Here, to determine the parameters in constitutive equations of muscles, an experimental method in vivo state including measurement of the integrated EMG is proposed. Then, their constitutive parameters are identified based on the least square approach using the analogy with the FEM model. Finally, the validity of the identified results is discussed.
