Subvoxel‐Controlled Microfluidic Printing of Dual‐Material and Multi‐Structural Filaments (Adv. Mater. Technol. 1/2024)

Stretchable Structural Colors In article 2301150, Huawei Chen, Zihan Bai, Liwen Zhang, and co-workers devise a dynamically adjustable direct ink writing platform with a movable needle in a Y-shaped microfluidic nozzle, which enabling precise subvoxel control over the structure of the inner layer to print various complex structures filaments. Via the printing platform, wavy inner structures are manufactured for stretchable conductance-stable and triboelectric nanogenerator fibers to realize energy harvesting and self-powered sensing. Such subvoxel-controlled microfluidic printing significantly increases the complexity of dual-material filaments to provide potential applications for flexible electronics.
