The invention discloses a micro/nano array and application thereof in micro/nano material standard bending strain loading. The micro/nano support array is composed of a substrate and a plurality of column-shaped structures which are located vertically on the substrate and are distributed at intervals to serve as supporting points. A micro/nano supporting dot matrix pattern can be defined freely. The micro/nano array is used for standard bending strain loading of quasi-one-dimensional micro/nano materials with different lengths and thicknesses, and has great application prospects in development of microforce and displacement sensors, flexible micro-nano biology, photoelectric detection and many other aspects.
