Tendons exhibit piezoelectric properties, whose mechanical properties are determined by the orientation of collagen fibers. We observed the anisotropy of acoustically induced polarization in fibrous tissue by detecting piezoelectric polarization (acoustically induced polarization) induced by ultrasound. The purpose of this study is to clarify the relationship between the anisotropy of acoustically induced polarization in tendon tissue and its mechanical properties. In this presentation, we will conduct tensile tests on bovine Achilles tendons and discuss the correlation between Young's modulus and anisotropy of acoustically induced polarization.
