“…The high‐resolution XPS spectra of C1s (Figure 3d) were deconvoluted into the peaks at 284.5, 285.4, and 290.1 eV, corresponding to C=C, C–C, and COOH, respectively. [ 35,36 ] Comparing high‐resolution C1s XPS of PES film and PES‐LIG (Figure S3b, Supporting Information), the intensity of the C1s peaks for oxygen‐containing C1s functional groups is reduced in PES‐LIG. An obvious change in surface wettability of PES‐LIG was also observed, where the superhydrophilic surface of pristine PES membrane (inset of Figure S3b, Supporting Information) was converted to a moderately hydrophobic LIG surface with a contact angle of 115°.…”

The laser‐induced graphene (LIG) has a great potential in electrochemically active electrodes for wearable biosensors. Herein, for the first time, a stretchable and non‐enzymatic glucose sensor based on LIG derived from commercial poly(ether sulfone) (PES) membranes is reported. The LIG is in situ transferred onto an elastomer and tightly wrapped by the elastomer in one laser carbonization step. Superior to the conventional casting and demolding transfer process, this method avoids the LIG's morphology distortion and loss. By adjusting the laser settings and the patterns, hierarchically structured electrodes are prepared with greatly increased surface areas for glucose detection. The electrodeposited dendritic gold‐nanoparticles act as the catalyst for glucose sensing. The optimized flexible sensor demonstrates a linear range for glucose from 10 μm to 10.0 mm and a detection limit of 26 μm. The sensor shows a sensitivity of 0.024 ± 0.001 mA mm−1 and selectivity toward other interfering metabolites, as well as excellent performance under mechanical bending (stable performance after 500 bending cycles) and stretchability (resistance unchanged after 1000 cyclic stretching at 20% strain). Due to the simplicity of preparation and extraordinary fidelity, the novel PES‐LIG sensor is a promising candidate for the next generation of skin‐adherent diagnostic devices and wearable electronics.

“…To address the above issue, researchers have focused on combining 3D printing with metallization techniques to create conductive structures. Several studies have attempted to replace 3D metal–plastic structures used in areas such as electronics with various conductive materials, including metallic nanoparticles, , graphene, , multiwalled carbon nanotubes, and carbon black . These substances are often used as conductive fillers to obtain modified materials that can be applied to 3D printing.…”

Constructing precise metal patterns on complex three-dimensional (3D) plastic parts allows the fabrication of functional devices for advanced applications. However, it is currently expensive and requires complex processes. This study demonstrates a process for the fabrication of 3D metal–plastic composite structures with arbitrarily complex shapes. A light-cured resin is modified to prepare the active precursor allowing subsequent electroless plating (ELP). A multimaterial digital light processing 3D printer was newly developed to fabricate the parts containing regions made of either standard resin or active precursor nested within each other. Selective 3D ELP processing of such parts provided various metal–plastic composite parts having complicated hollow structures with specific topological relationships with the resolution of 40 μm. Using this technique, 3D devices that cannot be manufactured by traditional methods are possible, and metal patterns can be produced inside plastic parts as a means of further miniaturizing electronics. The proposed method can also generate metal coatings exhibiting improved adhesion of metal to substrate. Finally, several sensors composed of different functional materials and specific metal patterns were designed and fabricated. The present results demonstrate the viability of the proposed method and suggest potential applications in the fields of 3D electronics, wearable devices, and sensors.

Flexible, wearable pressure sensors have been widely studied in the fields of motion detection, health management, and human−computer interaction. However, the unsatisfactory stability and durability limit its application, due to the weak interface interaction between the flexible substrate and conductive layer. Herein, we design a wearable pressure sensor with good sensitivity and stability by integrating a conductive cellulose/exfoliated graphene (CEG) ink with polyethylenimine-modified cotton fabrics (PEI-CFs). The negatively charged graphene was obtained via liquid-phase exfoliation of graphite in a sustainable cellulose solution. The pressure sensor was prepared by an electrostatic self-assembly process in which negatively charged CEG is adsorbed to the positively charged PEI-CFs. In this strategy, CEG ink combines firmly with the PEI-CF substrate, endowing the as-prepared pressure sensor with stable sensing performance and longterm stability. Due to these advantages, it can be used for human health monitoring, such as human motion, breathing, and microexpression. This work provides a simple and feasible route for the development of stable, durable, and high-performance wearable electronics.
