Every corner of advanced R&D seems to head toward micronization. Micronization research in mechanics started recently but an intensive and comprehensive approach has been taken since 1992 when both the government R&D project and Micromachine Center were initiated. Micromachine is a new technological paradigm and has the same potential benefit as today's macromachine. Micromachine will take considerable time span to be completed for full-fledge application. Until then, a wide range of approaches, i.e. R&D, dissemination, international exchange are indispensable.
