Outline of Final Research Achievements

1) MEMS fabrication : We have fabricated MEMS device and built custom-designed experimental setup which can measure friction/normal forces while observing actual contact area.
2) Single nano-asperity friction: The setup enabled us to observe single nano-asperity friction.
3) Another materials : We observed the actual contact area of Fe, PTFE, Pt and Ru and obtained the difference.
