Among the most important and landmark structures in nature, helical objects are an emerging group of materials with unique spiral geometry, and because of their enriched physical and chemical properties, they can have multiple functionalities. However, the fabrication of such complex helical materials at the micro- or nanoscale level remains a challenge. Here will present a coaxial capillary microfluidic system with the functions of consecutive spinning and spiraling, for scalable generation of helical microfibers.    The length, diameter, and pitch of the helical microfibers are highly controllable due to the precisely tunable flow rates. Varying the injection capillary design of the microfluidics can enable the generation of helical microfibers with structures such as the novel Janus, triplex, coreshell, and even double-helix. The potential use of these helical microfibers for magnetic and thermodynamic triggered micro-spring, as well as for a force indicator of cardiomyocytes contraction have also been explored, as schemed in Figure 1. These indicate that such helical microfibers are highly versatile for different applications.
