Portable and wearable sensors have attracted considerable attention in the healthcare field because they can be worn or implanted into a human body to monitor environmental information. However, sensors cannot work independently and require power. Flexible in‐plane micro‐supercapacitor (MSC) is a suitable power device that can be integrated with sensors on a single chip. Meanwhile, paper is an ideal flexible substrate because it is cheap and disposable and has a porous and rough surface that enhances interface adhesion with electronic devices. In this study, a new strategy to integrate MSCs, which have excellent electrochemical and mechanical performances, with sensors on a single piece of paper is proposed. The integration is achieved by printing Ni circuit on paper without using a precoating underlay. Ink diffusion is also addressed to some degree. Meanwhile, a UV sensor is integrated on a single paper, and the as‐integrated device shows good sensing and self‐powering capabilities. MSCs can also be integrated with a gas sensor on one‐piece paper and can be charged by connecting it to a solar cell. Thus, it is potentially feasible that a flexible paper can be used for integrating MSCs with solar cell and various sensors to generate, store, and use energy.

用于在一张纸上集成设备的平面微型超级电容器

便携式和可穿戴传感器在医疗保健领域引起了相当大的关注，因为它们可以被穿戴或植入人体中以监测环境信息。但是，传感器无法独立工作并且需要电源。柔性平面微型超级电容器（MSC）是可以与传感器集成在单个芯片上的合适功率设备。同时，纸是理想的柔性基材，因为它便宜且可抛弃，并且具有多孔且粗糙的表面，可增强与电子设备的界面粘合性。在这项研究中，提出了一种将具有优异电化学和机械性能的MSC与传感器集成在一张纸上的新策略。通过在纸上印刷镍电路而不使用预涂层底衬来实现集成。墨水扩散也得到了一定程度的解决。同时，UV传感器集成在一张纸上，并且集成的设备显示出良好的感应和自供电功能。MSC还可以与气体传感器集成在一张纸上，并且可以通过将其连接到太阳能电池上进行充电。因此，柔性纸可用于将MSC与太阳能电池和各种传感器集成在一起以产生，存储和使用能量是潜在可行的。
