Fabricating electronic devices from natural, renewable resources is a common goal in engineering and materials science. In this regard, carbon is of special significance due to its biocompatibility combined with electrical conductivity and electrochemical stability. In microelectronics, however, carbon's device application is often inhibited by tedious and expensive preparation processes and a lack of control over processing and material parameters. Laser‐assisted carbonization is emerging as a tool for the precise and selective synthesis of functional carbon‐based materials for flexible device applications. In contrast to conventional carbonization via in‐furnace pyrolysis, laser‐carbonization is induced photo‐thermally and occurs on the time‐scale of milliseconds. By careful selection of the precursors and process parameters, the properties of this so‐called laser‐patterned carbon (LP‐C) such as porosity, surface polarity, functional groups, degree of graphitization, charge‐carrier structure, etc. can be tuned. In this critical review, a common perspective is generated on laser‐carbonization in the context of general carbonization strategies, fundamentals of laser‐induced materials processing, and flexible electronic applications, like electrodes for sensors, electrocatalysts, energy storage, or antennas. An attempt is made to have equal emphasis on material processing and application aspects such that this emerging technology can be optimally positioned in the broader context of carbon‐based microfabrication.

“…In an air atmosphere, precarbonization of cotton cloth was carried out in muffle furnace at 300 °C for 2 h. The obtained carbonized cloth was placed in a plastic mold for PDMS (Sylgard 184, Dow Corning, mixing ratio 10:1) casting as previously proposed for other LIG‐based materials. [ 56 ] Air was evacuated from liquid PDMS to allow full infiltration of the viscous elastomer into carbonized cloth, then the PDMS was crosslinked at 80 °C for 3, 4, 5, 6, 7, 8, and 9 min in a convection oven, respectively. The carbonized cloth was placed on the precured PDMS and sank inside with tunable depth because the viscosity of liquid PDMS was controlled by precuring time.…”

date, a variety of active layers including silver nanowires, [10] conductive polymers, [13] and graphene [14,15] have been used to prepare pressure sensors on elastomer substrates by infilling, [16] lithography, [17] screen, or inject-printing techniques. [18] Nevertheless, these methods are either limited by high-cost and complex technical routes, or involve high temperature and toxic processes, which cannot be truly adapted to green, health-focused wearable devices. [19][20][21][22] Therefore, it remains a daunting challenge to build flexible pressure sensors in a facile, cost-effective, and large-area-capable manner. [23][24][25] In 2014, Tour's group reported that the commercial polyimide (PI, Kapton) film can be directly converted into graphene by CO 2 laser scribing, which has attracted widespread attention. [26] Compared with conventional graphene synthesis methods such as mechanical stripping, chemical vapor deposition and chemical reduction, laser scribing enables large-scale, noncontact, mask-free production in an atmospheric environment. [27,28] The resulting product, known as laser-induced graphene (LIG), shows a 3D porous structure with high specific surface area (≈340 m 2 g −1 ), high thermal stability (>900 °C) and excellent sheet resistance (10 Ω sq −1 ) that can be assembled into different flexible sensors for accurate measurement of hydration, [29] strain, [30] pressure, [14,31] temperature, [32] and other parameters of interest. [33,34] Groundbreaking studies have also found the LIG can be synthesis using multiple pulsed-laser irradiation of carbon precursors including natural materials, [35] food, [36] and even nonpolymer materials. [37,38] However, there are still two challenges to achieve high-quality conversion of LIG. First, natural materials contain more combustible substances, such as proteins, sugars and lignin, than polymers. [39,40] The precursor is first amorphous carbonized and then converted to LIG, which usually requires multiple or defocused laser irradiation and the addition of commercial flame retardants. [41] Second, both from polymers and natural resources, the mechanical properties of LIG are poor while the inherent stiffness cannot meet the inevitable deformation in daily use. [14,42,43] A strategy was developed to remedy this deficiency by transferring the LIG obtained from original platform to elastomers. [5,44] Unfortunately, a significant improvement in flexibility is accompanied by a reduction in electrical properties (sheet resistance down from ≈10 to ≈60 Ω sq −1 ), because Latest advances have witnessed the laser scribing of various active materials from synthetic polymers to natural sources without masks, post-treatment, or toxic substances. However, laser induced graphene (LIG) on renewable precursors usually requires flame-retardant pretreatment and multistep pulsed or defocused irradiation. Laser scribing of silicon carbide (SiC) from polydimethylsiloxane (PDMS) is limited by its high transparency over a broad wavelength range. Here, a structural design strategy ...

“…27,38,39 As the second category, flexible substrates (polymer, paper, and textile cloth) have been incorporated into foldable and wearable devices. [40][41][42][43] To evaluate the electrochemical performance of PMSCs, conventional test parameters should be finely tuned based on the planar configuration. The measurement units need to be changed to the area and volume of PMSCs instead of the mass of active materials.…”
