摘要
This study introduces the approach for precisely controlling the trajectory of fluid jets by employing electric field manipulation to confine fiber deposition to specific areas on flexible substrates, particularly within various electronic device applications. Applying similar polar high voltage to both the nozzle tip and printed circuit board generates complementary electric fields, directing the fluid jet to the desired locations on the flexible substrate. This innovative technique eliminates the necessity for traditional masking methods, resulting in reduced ink consumption, streamlined production processes, and minimized chemical waste. To illustrate practical applications, we fabricate flexible conductive electrodes for media façade applications and real-time sensor monitoring, showcasing the effectiveness of integrating Ag nanoparticles into functional electronic components. With an approximate sheet resistance of 10 Ω/sq2, our system adeptly controls Ag nanoparticle deposition within defined areas. This approach not only aligns fibers precisely but also ensures uniform deposition, making it ideal for various flexible applications. Overall, this study underscores the potential of electric field manipulation to revolutionize surface and coating technology, offering a promising avenue for sustainable and efficient manufacturing processes, particularly in flexible applications. The resulting patterned electrodes can be employed in a wide range of flexible electronic devices, contributing to more sustainable and efficient manufacturing processes in the industry.
