便携式和可穿戴电子产品的快速发展要求开发高性能、小型化的储能设备，这些设备具有灵活的外形因素和高能量和功率传输。印刷微型超级电容器（MSCs）具有平面内数字间配置，被吹捧为满足这些要求的有前途的选择。新的印刷技术可以组装MSCs，具有财政和环境效益，大尺寸，高吞吐量，传统微加工技术无法提供的质量。本文介绍了用于可穿戴MSCs的功能墨水系统的制备的最新进展，包括电极材料、导体材料和电解质。首先，介绍了印刷技术基础的全面背景，重点讨论了在保持良好印刷性的同时提高油墨功能的方法。其次，探索了各种印刷技术，以确保具有高表面电化学性能和小足迹的可穿戴MSCs的可制造缩放。在这两个主题的范围内，讨论了阻碍印刷MSC广泛采用的充分具体化的各种问题以及克服这些问题的下一步措施。进一步深入探讨了科学和技术挑战，包括油墨的有限功能，低打印分辨率，覆盖精度，和复杂的封装。
The rapid progression of portable and wearable electronics has necessitated the development of high-performing, miniaturized energy-storage devices with flexible form factors and high energy and power delivery. Printed micro-supercapacitors (MSCs), with in-plane interdigital configurations, is touted as a promising choice to fulfill these requirements. New printing technologies can assemble MSCs with fiscal and environmental benefits, large form factors, and at high throughputs, qualities not afforded with conventional microfabrication technologies. Here, recent progress in the preparation of functional ink systems for wearable MSCs, encompassing electrode materials, conductor materials, and electrolytes, is presented. First, a comprehensive background of the fundamentals of printing technology is introduced, with discussions focusing on methods of improving ink functionality while simultaneously retaining good printability. Second, various printing techniques to ensure manufacturable scaling of wearable MSCs with high areal electrochemical performance and small footprint are explored. Within the scope of these two topics, various issues that hinder the full materialization of widespread adoption of printed MSC and next steps to overcome these issues are discussed. Further deep dives in scientific and technical challenges are also presented, including limited functionality of the inks, low printing resolution, overlay accuracy, and complex encapsulation.
