Research Abstract
Focusing on the hemispherical dimple structure in articular cartilage, we modified a similar shape on the surface of hydrogel, which is treated as a model material for biological tissues. The friction force of the gel was found to be reduced by about 50% due to the dimple structure under certain conditions, and the mechanism was further clarified by measuring the adhesion force and observing the friction interface. In addition, a new evaluation method for wear caused by friction was established for the application of gel as a substitute material for living bodies. It is now possible to evaluate the amount of wear by quantifying the gel-derived polymers present in the lubricant using ultraviolet absorption spectra.
