Research on the biomechanics of the skin.
The human skin consists of four layers: the stratum corneum (approximately 20 μm thick, but over 0.5 mm thick on the palms and soles), the epidermal layer (approximately 40 μm thick), the dermis (approximately 1.3 mm thick), and the subcutaneous tissue (several mm to tens of mm thick). These layers have completely different structures, leading to diverse elastic properties that are expected to significantly influence the physiology, pathology, and beauty of the skin.
Furthermore, using animal skin samples, we conduct uniaxial and biaxial tensile tests to precisely measure the mechanical properties of each skin layer. We are also conducting research from a biomechanical perspective to explore the mechanisms of wrinkle formation.
In our laboratory, we have developed and continuously improved a device for measuring the elastic properties of each layer of the skin in collaboration with private enterprises. We are measuring changes in the elastic properties of human skin under various conditions. By combining experimental results with finite element analysis, we aim to establish methods to elucidate the elastic properties of each layer of human skin. Additionally, we are exploring methods to estimate similar responses based on shear deformation applied to the skin surface under various conditions.
