“…Later, with the rapid development of wearable and portable electronics, the planer macro‐/microenergy devices have attracted widespread attention. The construction of in‐plane energy devices with interdigital or helical electrodes structures is achieved by means of various technologies, such as laser micronano processing, template imprint, screen printing, photolithography, three‐dimensional (3D) printing, and so on 40–42 . In recent years, our group prepared a variety of planar supercapacitors and batteries mainly based on laser direct writing or laser‐assisted technology.…”

The vigorous development in the field of energy conversion and storage devices directly contributes to the full utilization and convenient use of clean energy. However, some drawbacks of independent energy conversion and storage devices, including unstable, insufficient energy output and dependence on external power supply, are difficult to overcome by self‐optimization, thus, hindering their further development and direct application. Coincidentally, the combination of above two devices can solve these problems, which conforms to their intrinsic needs for development. At the same time, the pursuit of portability and miniaturization also promotes the development of the power system toward a highly integrated direction. Therefore, we introduce several integration modes of energy conversion and storage systems, with emphasis on all‐in‐one power system, possessing the highest integration in this review. From the aspect of device configuration, working mechanisms and their performances, the all‐in‐one power systems based on different energy sources (e.g., mechanical, solar, thermal, and chemical energy) are discussed and analyzed. Finally, the design strategies are summarized and the potential development directions in the future are proposed. This review aims to provide a comprehensive overview of highly integrated energy conversion and storage system, and seeks to point out the opportunities and orientations of future research in this field.

“…Nowadays, a chief challenge related to MSCs is to reduce the feature size, including the microelectrode length, width, and gap between adjacent microelectrodes, which would greatly influence the integration level, reaction kinetics, areal operating voltage, and energy density. Thereby, many reported studies focused on the high-precision microfabrication techniques, such as photolithography [27], laser scribing technique [28][29][30], focused ion beam (FIB) etching [18,21,31], and printing methods [32][33][34]. Besides, considerable attention has been paid to improving electrochemical performance, which was usually sacrificed with the reduction in the size of MSCs [33,35], resulting from poor compatibility between electrode materials and multistep complex microfabrication process, such as temperature change or inevitable chemical corrosion and residue.…”

Ultracompact and customizable micro-supercapacitors (MSCs) are highly demanded for powering microscale electronics of 5G and Internet of Things technologies. So far, tremendous efforts have been concentrated on fabricating high-performance MSCs; however, compatible fabrication and monolithic integration of MSCs with microelectronic systems still remains a huge challenge taking into full consideration the factors such as electrode film fabrication, high-resolution microelectrode pattern, and electrolyte precise deposition. In this review, we summarize the recent advances of ultrasmall and integrated MSCs with tunable performance and customizable function, including key microfabrication technologies for patterning microelectrodes with superior resolution, precise deposition of customized electrolytes in an extremely small space, and feasible strategies for improving electrochemical performance by constructing thick microelectrodes and special electrode structure. Finally, the related challenges and key prospects of ultracompact and customizable MSCs, including compatible microfabrication methods for electrode materials and films, patterning microelectrodes, customizing shape-conformable electrolytes, performance optimization, and efficient integration with microelectronic systems, are put forward for further promoting their practical application.

“…1) [5,11,12,54,[77][78][79]. To date, although some reviews have partially mentioned multifunctional PMSCs and their functional integration [80][81][82], most reviews on PMSCs mainly focus on high-performance electrode materials and advanced fabrication methods [62,[80][81][82][83][84][85][86][87]. To the best of our knowledge, no study has offered a comprehensive summary of the design, construction, applications, and challenges of PMSCbased multifunctional devices, including multifunctional PMSCs and their multifunctional integration.…”

With the boom of portable, wearable, and implantable smart electronics in the last decade, the demand for multifunctional microscale electrochemical energy storage devices has increased. Owing to their excellent rate performance, high power density, long cycling lifetime, easy fabrication, and integration, multifunctional planar microsupercapacitors (PMSCs) are deemed as one of the ideal micropower sources for next-generation flexible on-chip electronics. Therefore, we offer a comprehensive overview of the recent progress regarding multifunctional devices based on PMSCs, including stretchable, self-healing, stimulus-responsive, thermosensitive, biodegradable, and temperaturetolerant microdevices. We also emphasize the unique applications of multifunctionally integrated PMSCs in the construction of self-powered and sensor-integrated systems in terms of multifunctional operation modes. Finally, the key challenges and future prospects related to these multifunctional devices are discussed to stimulate further research in this flourishing field.
