Description

technical field [0001] The invention belongs to the technical field of soft condensed matter manufacturing, and in particular relates to an extreme manufacturing device and a use method of a microdroplet three-dimensional spherical structure. Background technique [0002] Soft matter, also known as soft condensed matter, includes liquid crystal, colloid, macromolecule, particulate matter, living system matter (such as DNA, protein, cell membrane), emulsion, etc. far-reaching. In recent decades, the micro-nano processing technology for solid materials has realized the integration of complex electronic functions on electronic devices on the micrometer scale, which has contributed to the rapid development of the modern electronic industry, especially the semiconductor industry. Since the macroscopic properties of smart flexible materials depend on their chemical composition and microstructure, micro-nano-fabrication technologies for liquid and soft matter materials are critica...
