In the present study, a measurement system for foot pressure distribution in walking are developed. This problem has some difficulties owing to the change of the boundary conditions in the contact area if sensors are directly put on the surface. In order to overcome the difficulties, this present system, the strain informations are measured apart from the contact area, and inverse analysis is applied to obtain pressure distribution acting on the surface of the structure. On the process of the inverse analysis, some regularization technique, Tikhonov method and truncating singular value decomposition (TSVD), are employed to avoid the instability of the numerical solutions. Pressure distribution measurement examination when walking acting on the load cell is performed to confirm the validity of the present method
