Mechanical Properties of Hydrogel using Nanoindentation

In this application, the Nanovea Mechanical Tester, in Nanoindentation mode, is used to study the hardness, elastic modulus and creep mechanical properties of a Hydrogel sample. In this case a sample of Hydrogel can simply be placed on a glass slide due to the softness and low load being used to test; testing could also be preformed while in liquid. For this soft material a 3mm spherical tip will be used. This is to give good information on the Hydrogel and not on surface properties that might be different. This can be studied using a shaper Berkovich tip.
