With the advent of Internet of Things (IoTs) and wearable devices, manufacturing requirements have shifted toward miniaturization, flexibility, environmentalization, and customization. Inkjet printing, as a non-contact picoliter-level droplet printing technology, can achieve material deposition at the microscopic level, helping to achieve high resolution and high precision patterned design. Meanwhile, inkjet printing has the advantages of simple process, high printing efficiency, mask-free digital printing, and direct pattern deposition, and is gradually emerging as a promising technology to meet such new requirements. However, there is a long way to go in constructing functional materials and emerging devices due to the uncommercialized ink materials, complicated film-forming process, and geometrically/functionally mismatched interface, limiting film quality and device applications. Herein, recent developments in working mechanisms, functional ink systems, droplet ejection and flight process, droplet drying process, as well as emerging multifunctional and intelligence applications including optics, electronics, sensors, and energy storage and conversion devices is reviewed. Finally, it is also highlight some of the critical challenges and research opportunities. The review is anticipated to provide a systematic comprehension and valuable insights for inkjet printing, thereby facilitating the advancement of their emerging applications.
随着物联网（IoTs）和可穿戴设备的出现，制造需求已转向小型化、灵活性、环保化和定制化。喷墨打印作为一种非接触式皮升级液滴打印技术，能够在微观层面实现材料沉积，有助于实现高分辨率和高精度的图案化设计。同时，喷墨打印具有工艺简单、打印效率高、无掩膜数字打印以及直接图案沉积等优点，正逐渐成为满足此类新需求的一项有前景的技术。然而，由于墨水材料未商业化、成膜过程复杂以及几何/功能不匹配的界面，在构建功能材料和新兴器件方面仍有很长的路要走，这限制了薄膜质量和器件应用。在此，本文综述了喷墨打印在工作机制、功能墨水体系、液滴喷射与飞行过程、液滴干燥过程以及包括光学、电子、传感器和储能与转换器件在内的新兴多功能及智能应用方面的最新进展。最后，还强调了一些关键挑战和研究机遇。预计该综述将为喷墨打印提供系统的理解和有价值的见解，从而推动其新兴应用的发展。
