评估了三种市售导电丝在纸上 3D 打印柔性电路的效果。虽然所有三种细丝均已成功打印，但通过电化学阻抗谱表征时，发现所得导电迹线具有显着不同的阻抗。使用石墨掺杂的聚乳酸丝，评估了纸基导电迹线的柔韧性，演示了将常见电气和电子元件与导电迹线集成的方法，并对迹线的电阻加热进行了表征。使用商用材料在纸上 3D 打印导电迹线的能力为柔性电子产品的快速原型制作以及将电子电路与纸基微流体设备集成提供了许多机会。
Three commercially-available conductive filaments were evaluated for 3D printing flexible circuits on paper. While all three filaments were printed successfully, the resulting conductive traces were found to have significantly different impedances when characterized by electrochemical impedance spectroscopy. Using a graphite-doped polylactic acid filament, the flexibility of paper-based conductive traces was evaluated, methods of integrating common electrical and electronic components with the conductive traces were demonstrated, and the resistive heating of the traces was characterized. The ability to 3D print conductive traces on paper using commercially available materials opens many opportunities for rapid prototyping of flexible electronics and for integrating electronic circuits with paper-based microfluidic devices.
