对柔性和可穿戴混合电子产品的需求不断增长，引发了对具有多功能打印能力的先进制造技术的需求。复杂的油墨配方、表面活性剂/污染物的使用、有限的源材料以及对用于烧结的高温热处理的需要是当前喷墨和气溶胶印刷方法面临的主要问题。在这里，纳米制造的柔性混合电子（FHE）的干印刷银和铟锡氧化物的柔性基板上使用一种新的激光为基础的添加剂纳米制造过程的报告。在打印过程中，通过调整打印样品的几何形状和结构来定制打印线的电阻。不同的FHE设计制造和测试，以检查设备的性能。包括循环、弯曲和拉伸在内的机械可靠性测试证实了打印样品在不同应变水平下的预期性能。这种变革性的无液体工艺允许按需形成和原位激光结晶纳米颗粒，用于打印未来柔性和可穿戴电子产品和传感器的纯材料。
The growing demand for flexible and wearable hybrid electronics has triggered the need for advanced manufacturing techniques with versatile printing capabilities. Complex ink formulations, use of surfactants/contaminants, limited source materials, and the need for high-temperature heat treatments for sintering are major issues facing the current inkjet and aerosol printing methods. Here, the nanomanufacturing of flexible hybrid electronics (FHE) by dry printing silver and indium tin oxide on flexible substrates using a novel laser-based additive nanomanufacturing process is reported. The electrical resistance of the printed lines is tailored during the print process by tuning the geometry and structure of the printed samples. Different FHE designs are fabricated and tested to check the performance of the devices. Mechanical reliability tests including cycling, bending, and stretching confirm the expected performance of the printed samples under different strain levels. This transformative liquid-free process allows the on-demand formation and in situ laser crystallization of nanoparticles for printing pure materials for future flexible and wearable electronics and sensors.
