    Amniotic membrane (AM) is utilized in tissue engineering due to its advantages such as immune tolerance. However its mechanical characteristics has not been thoroughly investigated. In this study, we employed uniaxial tensile apparatus to investigate the directionality, viscoelasticity, and strength of porcine AM. The experimental results show that AM is isotropic but heterogeneous. The strength of the AM near placenta is 2.3±1.0 [MPa], higher than those of all other portions. The coefficients of stress relaxation of the AM near placenta (λ<inf>1</inf>=14.7±4.7 [s]; λ<inf>2</inf>=37.3±5.7 [s]) is also the largest.
