Anisotropically compartmentalized microparticles are increasingly interested in the field of sensing, drug delivery and micro-actuator because their characteristic morphologies. Herein, we introduce modified electrohydrodynamic (EHD) co-jetting method for helically decorated micro-building block. The helically decorated micro fiber can be obtained via double rotating collector, and then the microcylindrical structure of them can be obtained by cryo-sectioning of microfibers bundles. In addition, these microcylinders change their shape from microcylinder to microsphere with distinct compartmentalization and unique microstructures by external stimuli. These techniques can provide spiral microstructures and can be extended to mimicking biological micro-organisms.
