“…Laser-induced graphene (LIG) technology is a promising graphene preparation strategy, which can convert carbon precursor materials into patterned three-dimensional (3D) porous graphene in a single step using a laser under ambient conditions . The final product, which is LIG, has multiple advantages, including high mechanical stability, superior electrical conductivity, and ease of preparation, making it suitable for various applications such as microsupercapacitors, − electric heaters, − and flexible sensors. − Numerous flexible strain sensors have recently been developed by using the LIG technology. Researchers have primarily employed laser irradiation on polyimide (PI) − or poly(ether–ether–ketone) (PEEK) substrates to prepare LIG as a sensing layer for flexible strain sensors.…”

Laser-induced graphene prepared on polymer substrates with a high modulus is a widely applied method to fabricate varied flexible electronics; however, the resulting relatively poor stretchability considerably limits its applicability. In this paper, an elastic composite consisting of poly(ether−ether−ketone) powder and poly(dimethylsiloxane) (PDMS) is reported to fabricate stretchable electrodes using direct laser-induced graphitization without transferring. The liquid composites before curing can be cast into various shapes for different applications. To balance the conductivity and stretchability of stretchable electrodes, we optimized the composite mass ratios and laser parameters and performed a series of morphological and performance characterizations on the composites; furthermore, we analyzed the elemental composition and functional groups of the laser-induced products. With the proper encapsulating method, strain sensors were prepared, exhibiting high sensitivity (a gauge factor of 78) and a stable resistance response over 50% operating range with the ability to monitor both fine pulse beats and larger strains such as human joint movement. Furthermore, a humidity sensor composited with laser-patterned interdigital electrode and graphene oxide on the elastic composite substrate had characteristics of high sensitivity (14.18 pF/%RH) and fast recovery time (9 s), which could be used for breathing monitoring and noncontact sensing. In conclusion, laser-induced graphene prepared in one step on a stretchable composite film of polymers with a high modulus and low modulus is a promising method to fabricate wearable electronics.

“…In addition, as previously shown in Figure B, the produced LIG layer is very thin (less than 50 μm). Therefore, the obtained specific capacitance should in principle be lower than the values obtained for thicker and porous substrates such as paper , and other cellulose-based materials, ,− for instance. Moreover, higher capacitances have also been obtained for doped graphene/LIG electrodes , or systems prepared by more complicated or expensive methods. , Nevertheless, the specific capacitance achieved represents a good result considering the lower LIG thickness and undoped nature.…”

Laser irradiation of polymeric materials has drawn great attention as a fast, simple, and cost-effective method for the formation of porous graphene films that can be subsequently fabricated into low-cost and flexible electronic and energy-storage devices. In this work, we report a systematic study of the formation of laser-induced graphene (LIG) with sheet resistances as low as 9.4 Ω/sq on parylene-C ultrathin membranes under a CO2 infrared laser. Raman analysis proved the formation of the multilayered graphenic material, with I D/I G and I 2D/I G peak ratios of 0.42 and 0.65, respectively. As a proof of concept, parylene-C LIG was used as the electrode material for the fabrication of ultrathin, solid-state microsupercapacitors (MSCs) via a one-step, scalable, and cost-effective approach, aiming at future flexible and wearable applications. The produced LIG-MSC on parylene-C exhibited good electrochemical behavior, with a specific capacitance of 1.66 mF/cm2 and an excellent cycling stability of 96% after 10 000 cycles (0.5 mA/cm2). This work allows one to further extend the knowledge in LIG processes, widening the group of precursor materials as well as promoting future applications. Furthermore, it reinforces the potential of parylene-C as a key material for next-generation biocompatible and flexible electronic devices.

“…Building upon this, Lv et al employed a piezoelectric on-demand inkjet printer for reactive inkjet printing, where two reactive components are printed on top of each other to trigger a reaction and form a Of course, in addition to using expensive gold and silver solutions to print flexible electronic patterns, researchers are actively exploring alternative methods to reduce costs. Lv et al [94] utilized graphene printing [56,[95][96][97][98], a more affordable option, to fabricate flexible circuits and radio frequency (RF) antennas. Unlike gold and silver solutions, graphene printing material does not require the addition of stabilizers to disperse them, thereby avoiding any adverse effects on circuit conductivity.…”

Given the advancements in modern living standards and technological development, conventional smart devices have proven inadequate in meeting the demands for a high-quality lifestyle. Therefore, a revolution is necessary to overcome this impasse and facilitate the emergence of flexible electronics. Specifically, there is a growing focus on health detection, necessitating advanced flexible preparation technology for biosensor-based smart wearable devices. Nowadays, numerous flexible products are available on the market, such as electronic devices with flexible connections, bendable LED light arrays, and flexible radio frequency electronic tags for storing information. The manufacturing process of these devices is relatively straightforward, and their integration is uncomplicated. However, their functionality remains limited. Further research is necessary for the development of more intricate applications, such as intelligent wearables and energy storage systems. Taking smart wear as an example, it is worth noting that the current mainstream products on the market primarily consist of bracelet-type health testing equipment. They exhibit limited flexibility and can only be worn on the wrist for measurement purposes, which greatly limits their application diversity. Flexible energy storage and flexible display also face the same problem, so there is still a lot of room for development in the field of flexible electronics manufacturing. In this review, we provide a brief overview of the developmental history of flexible devices, systematically summarizing representative preparation methods and typical applications, identifying challenges, proposing solutions, and offering prospects for future development.
