摘要
A method for designing and processing a microcantilever-based probe with an irregular cross section applied in the ultra-low friction coefficient measurement at a nanoscale single-point contact includes: first, establishing a universal theoretical model of the friction coefficient measurement; then, combined with the structural features of the microcantilever-based probe with the irregular cross section, establishing a specific theoretical model of the friction coefficient measurement suitable for the microcantilever-based probe with the irregular cross section; and based on above, combined with constraint conditions such as the friction coefficient resolution, the loadable maximum positive pressure or the measurable minimum friction force, and the atomic force microscope characteristics, etc., designing the microcantilever-based probe with the irregular cross section meeting the measurement requirements.
