Hydrogel is known for its super absorbency of water allowing for a close resemblance in flexibility as natural tissue. This close resemblance has made Hydrogel a common choice not only in biomaterials, but also electronics, environment and consumer good application such as contact lens. The use and diversity in application have each their own unique needs and requirements. One such requirement will be known and controlled mechanical properties using nanoindentation.
