“…have received considerable attention because of their ability to measure a wide range of physical variables with good sensitivity, wide detection range, fast response time, mechanical robustness, and long-term stability owing to the superior properties of graphene. [119][120][121][122] Nevertheless, the difficulty of graphene synthesis is the main obstacle to the mass production of graphene sensors. In the past few years, the discovery of 3D porous LIG has opened a new avenue for the facile, efficient, and low-cost fabrication of high-performance physical sensors.…”

“…As a result, the LIG/PDMS composite was more sensitive to temperature variation than the LIG. To utilize this property, Kim et al [ 119 ] transferred LIG on wood to a PDMS substrate to fabricate flexible LIG/PDMS thermistors (Figure 14j). The as‐produced LIG/PDMS thermistors showed an ultrahigh sensitivity of 5.730% °C −1 between 20 and 85 °C, which surpasses most state‐of‐the‐art temperature sensors.…”

Laser‐induced graphene (LIG) is a newly emerging 3D porous material produced when irradiating a laser beam on certain carbon materials. LIG exhibits high porosity, excellent electrical conductivity, and good mechanical flexibility. Predesigned LIG patterns can be directly fabricated on diverse carbon materials with controllable microstructure, surface property, electrical conductivity, chemical composition, and heteroatom doping. This selective, low‐cost, chemical‐free, and maskless patterning technology minimizes the usage of raw materials, diminishes the environmental impact, and enables a wide range of applications ranging from academia to industry. In this review, the recent developments in 3D porous LIG are comprehensively summarized. The mechanism of LIG formation is first introduced with a focus on laser‐material interactions and material transformations during laser irradiation. The effects of laser types, fabrication parameters, and lasing environment on LIG structures and properties are thoroughly discussed. The potentials of LIG for advanced applications including biosensors, physical sensors, supercapacitors, batteries, triboelectric nanogenerators, and so on are also highlighted. Finally, current challenges and future prospects of LIG research are discussed.

“…Figure 4e shows the response recovery time when the thermistor contacts with the ice sharply at room temperature. The responding time is 6 s, and the recovery time is 26 s. Compared with the preceding studies, 72 the faster responding−recovery time makes our copper-based thermistor respond quickly when the environment temperature changes. However, the thermistors fabricated on different substrates have different recovery time.…”

With the flexibilization tendency of traditional electronics, developing sensing devices for the low-temperature field is demanding. Here, we fabricated a flexible copper-based thermistor by a laser direct writing process with Cu ion precursors. The copper-based thermistor performs with excellent temperature sensing ability and high stability under different environments. We discussed the effect of laser power on the temperature sensitivity of the copper-based thermistor, explained the sensing mechanism of the as-written copper-based films, and fabricated a temperature sensor array for realizing temperature management in a specific zone. All of the investigations have demonstrated that such copper-based thermistors can be used as candidate devices for low-temperature sensing fields.

“…[ 202 ] Using the DLW technique on biodegradable substrates, Kim et al converted wood into LIG and transferred it to a flexible PDMS substrate. [ 177 ] The LIG thermistor respectively exhibited increase and decrease slopes of 5.5 and 5.6 K s −1 for 20% temperature changes over a range of 20–85 °C. The LIG sensor also demonstrated a positive temperature coefficient of 5.73% °C −1 .…”

“…Similarly, Kim et al fabricated a wood-derived LIG on a PDMS substrate to create a flexible thermistor using a UV femtosecond (FS) laser. [177] Although these low-cost biomaterialbased LIG electrodes were derived from biodegradable materials (lignin and wood as C precursors), the presence of PET and PDMS as substrates still invoked environmental issues because of the non-biodegradable properties of the substrates. Accordingly, the direct conversion of biodegradable substrates into LIG could be a compelling solution for fully green electronics.…”

As environmental issues have become the dominant agenda worldwide, the necessity for more environmentally friendly electronics has recently emerged. Accordingly, biodegradable or nature‐derived materials for green electronics have attracted increased interest. Initially, metal‐green hybrid electronics were extensively studied. Although these materials are partially biodegradable, they have high utility owing to their metallic components. Subsequently, C‐framed materials (such as graphite, cylindrical carbon nanomaterials, graphene, graphene oxide, laser‐induced graphene) have been investigated. This has led to the adoption of various strategies for C‐based materials, such as blending them with biodegradable materials. Moreover, various conductive polymers have been developed and researchers have studied their potential use in green electronics. Researchers have attempted to fabricate conductive polymer composites with high biodegradability by shortening the polymer chains. Furthermore, various physical, chemical, and biological sensors that are essential to modern society have been studied using biodegradable compounds. These recent advances in green electronics have paved the way toward their application in real life, providing a brighter future for society.This article is protected by copyright.
