“…Compared to photolithographic processes, direct laser writing of MSCs provides a less‐process intensive fabrication and more versatile route, although limited by its serial writing mode . Some parameters, including laser power and scanning speed, would have influence on the performance of the resulted RGO, e.g., electronic conductivity .…”

The continuous development of integrated electronics such as maintenance‐free biosensors, remote and mobile environmental sensors, wearable personal electronics, nanorobotics etc. and their continued miniaturization has led to an increasing demand for miniaturized energy storage units. Microsupercapacitors with graphene electrodes hold great promise as miniaturized, integrated power sources thanks to their fast charge/discharge rates, superior power performance, and long cycling stability. In addition, planar interdigitated electrodes also have the capability to reduce ion diffusion distances leading to a greatly improved electrochemical performance. Either as standalone power sources or complementing energy harvesting units, it is expected that graphene‐based microsupercapacitors will play a key role as miniaturized power sources in electronic microsystems. This review highlights the recent development, challenges, and perspectives in this area, with an emphasis on the link between material and geometry design of planar graphene‐based electrodes and their electrochemical performance and integrability.

direct laser scribing with a commercial CO 2 infrared laser system as found in most machine shops, the product being termed laser-induced graphene (LIG). [15] LIG exhibits high surface area (≈340 m 2 g −1 ), high thermal stability (>900 °C), and excellent conductivity (5-25 S cm −1 ). [15] The entire process can be performed in ambient air without any solvents, thereby making it exceedingly attractive for industrial use. This protocol combines the 3D graphene synthesis with writing into a single step process that has stimulated research ranging from fundamental studies on the transformation process to the development of a large variety of engineering applications. [15][16][17][18][19][20][21][22] Here, starting from the discovery of LIG, we will first emphasize strategies for the engineering of chemical, physical, and electronic properties of LIG; specifically, the regulation of laser parameters, atmosphere, and substrates to control the porosity, composition, and morphology of the LIG. The controllable synthesis of LIG and ease in property engineering makes it a versatile material in various applications including in sustainable energy conversions such as water splitting and fuel cell technology, [20,23] supercapacitors (SCs) for energy storage, [15,16,[24][25][26] sensors for sound, photon, strain, and chemicals detection, [27][28][29][30][31][32][33] and microfluidics [34][35][36] that are applicable to the laboratory and industrial scales, as outlined. Finally, the future advancement, such as the development of flexible electronics and biodegradable devices, will be discussed.Laser-induced graphene (LIG) is a 3D porous material prepared by direct laser writing with a CO 2 laser on carbon materials in ambient atmosphere. This technique combines 3D graphene preparation and patterning into a single step without the need for wet chemical steps. Since its discovery in 2014, LIG has attracted broad research interest, with several papers being published per month using this approach. These serve to delineate the mechanism of the LIG-forming process and to showcase the translation into many application areas. Herein, the strategies that have been developed to synthesize LIG are summarized, including the control of LIG properties such as porosity, composition, and surface characteristics, and the advancement in methodology to convert diverse carbon precursors into LIG. Taking advantage of the LIG properties, the applications of LIG in broad fields, such as microfluidics, sensors, and electrocatalysts, are highlighted. Finally, future development in biodegradable and biocompatible materials is briefly discussed. Laser-Induced Graphene
