Abstract

Nano-palpation technique based on atomic force microscopy is explained. The technique can be used to evaluate several materials' properties. The background theories of the technique is explained and the comparison with nano-indenter system was made to clarify the advantage of the technique. Hertzian contact theory and JKR theory are introduced for elastic contacts without and with adhesive interaction, respectively. The practical example studies such as rubber blend or paint material are also explained.
