Abstract: The development status of micronewton/nanonewton force measurement technology in recent years is introduced. The measurement methods, measurement and research results of micronewton/nanonewton force value are compared, and the characteristics and applicability of different test methods are pointed out. Based on the current development trend of micronewton/nanonewton force measurement field and combined with the development needs of the industry, the problems needing attention in the research of micro nano force measurement technology are put forward.

Key words: Micronewton/Nanonewton force, Measuring technology, Measuring uncertainty
