| Research Abstract |
With global environmental and energy problems becoming increasingly serious, the development of energy saving technologies is now considered a high priority. In present research, low frictional coatings were realized by using the piezoelectric material coatings of zinc oxide. It was revealed that a phenomenon in which the piezoelectric effect of zinc oxide functions due to pressure applied from an indenter, generating a repulsion force. This result is a basic technology which makes it possible to realize reductions in frictional force by the load resulting from gravity, without supplying any kinds of special energy in oil or vacuum conditions.
