Reduction of friction force by using a piezoelectric effect and development of low frictional coatings.

随着全球环境和能源问题的日益严重，节能技术的发展已成为当务之急。在目前的研究中，采用氧化锌压电材料涂层实现了低摩擦涂层。揭示了氧化锌的压电效应由于压头施加压力而产生排斥力的现象。这一结果是一项基本技术，可以实现由重力引起的负载减少摩擦力，而无需在油或真空条件下提供任何特殊能量。

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.
