“…The study was validated with body trials, including muscle contraction and pulse detection. Another strain sensor was made of LIG from KL and PVA, then transferred to a silicone elastomer . Since the LIG was embedded in an elastomer, the strain hysteresis was much lower compared to other strain sensors from synthetic precursors.…”

“…Compared to polysaccharides, lignins are characterized by a high C/O ratio and high thermal stability, features which makes lignin an excellent candidate precursor for LIG. Another good advantage of lignin is that it can be processed to obtain films, sheets, etc., thus easily be adapted to different application fields. ,, However, it is important to remark that, in order to produce films, lignin is often mixed with synthetic polymers to compensate for its bad mechanical properties, mainly brittleness; thus, the goal of replacing synthetic precursors is not fully achieved.…”

“…They were single-step scribed with a 10.6 μm CO 2 laser source in an ambient atmosphere, in one case in defocus conditions (Figure b) . They showed excellent results, both in sheet resistance measurements (2.8–4.5 Ω/□) and in Raman peak ratios ( I D / I G between 0.33 and 0.39 and I 2D / I G between 0.5 and 0.77). ,,, An interesting technique was to use a water lift-off process to remove the nonexposed parts of the films . This approach was improved by removing the need of dissolving the unused precursor: a forest-based ink for flexible and printed electronics has been obtained by combining LS and cellulose, with the addition of boric acid as FR, and screen-printed on polyethylene terephthalate (PET) sheets .…”

“…Another strain sensor was made of LIG from KL and PVA, then transferred to a silicone elastomer. 125 Since the LIG was embedded in an elastomer, the strain hysteresis was much lower compared to other strain sensors from synthetic precursors. The mechanism behind the increasing resistance was explained by the increasing distance between the individual embedded LIG flakes, as already reported in many cases.…”

The maskless and chemical-free conversion and patterning of synthetic polymer precursors into laser-induced graphene (LIG) via laser-induced pyrolysis is a relatively new but growing field. Bioderived precursors from lignocellulosic materials can also be converted to LIG, opening a path to sustainable and environmentally friendly applications. This review is designed as a starting point for researchers who are not familiar with LIG and/or who wish to switch to sustainable bioderived precursors for their applications. Bioderived precursors are described, and their performances (mainly crystallinity and sheet resistance of the obtained LIG) are compared. The three main fields of application are reviewed: supercapacitors and electrochemical and physical sensors. The key advantages and disadvantages of each precursor for each application are discussed and compared to those of a benchmark of polymer-derived LIG. LIG from bioderived precursors can match, or even outperform, its synthetic analogue and represents a viable and sometimes better alternative, also considering its low cost and biodegradability.

Direct Laser Writing (DLW) has been increasingly selected as a microfabrication route for efficient, cost‐effective, high‐resolution material synthesis and conversion. Concurrently, lasers participate in the patterning and assembly of functional geometries in several fields of application, of which electronics stand out. In this review, we survey and outline recent advances and strategies based on DLW for electronics microfabrication, based on laser material growth strategies. First, we summarize the main DLW parameters influencing material synthesis and transformation mechanisms, aimed at selective, tailored writing of conductive and semiconducting materials. Additive and transformative DLW processing mechanisms are discussed, to open space to explore several categories of materials directly synthesized or transformed for electronics microfabrication. These include metallic conductors, metal oxides, transition metal chalcogenides and carbides, laser‐induced graphene, and their mixtures. By accessing a wide range of material types, DLW‐based electronic applications are explored, including processing components, energy harvesting and storage, sensing, and bioelectronics. The expanded capability of lasers to participate in multiple fabrication steps at different implementation levels, from material engineering to device processing, indicates their future applicability to next‐generation electronics, where more accessible, green microfabrication approaches integrate lasers as comprehensive tools.This article is protected by copyright.

Lignin is a promising precursor to produce graphene materials due to its high carbon and aromatic contents. Upgrading lignin into graphene materials has gained significant interests as it offers a cost‐effective and sustainable route to produce high‐performance carbon materials. This review provides a comprehensive overview of the state‐of‐the‐art technologies on lignin to graphene materials with a focus on thermal catalytic and photothermal upgrading. The applications of lignin‐derived graphene materials and the perspectives for mass production of such graphene materials are also discussed.
