“…Laser manufacturing has become increasingly popular in material fabrication due to its high throughput and patterning capability. Recently, it was demonstrated that a commercial CO 2 infrared laser scriber can be used to in situ form and pattern 3D porous graphene on polyimide (PI), cloth, paper, and food under ambient conditions. In comparison to the laser‐reduced graphene method, which uses a laser to reduce graphene oxide (GO) films to graphene, the new laser‐induced graphene (LIG) method avoids the use of GO precursors and directly exploits the substrate materials as a carbon source, which greatly simplifies the fabrication process and reduces the cost .…”

In the past decade, graphene has shown great value in both fundamental sciences and practical applications. In spite of the intense research efforts on achieving chemical‐free, low‐temperature processing of high‐quality graphene, cost‐effective synthetic methods to directly fabricate graphene sheets on a substrate are still lacking. Laser‐induced graphene (LIG) is a recently developed method to directly form graphene from carbon‐rich materials. In this work, combined are theoretical and experimental approaches to systematically investigate the light‐material interactions in LIG fabrication processes. First, developed is a molecular dynamics model to disclose the transient formation process of LIG and identified are the critical parameters that govern this process. Following the theoretical prediction, developed is a system to utilize a picosecond UV laser to directly fabricate graphene from polyimide films at room temperature and under atmospheric pressure. After investigating the effects of the laser processing parameters on the LIG quality and subsequent processing optimization, it is experimentally demonstrated that picosecond UV laser processing can be used to prepare high‐quality LIG. With the newly developed LIG, fabricated is a high‐sensitive proximity sensor.

The increasing development of wearable, portable, implantable, and highly integrated electronic devices has led to an increasing demand for miniaturization of energy storage devices. In recent years, supercapacitors, as an energy storage device, have received enormous attention owing to their excellent properties of quick charge and discharge, high power density, and long life cycle with minimal maintenance. Micro-supercapacitors (MSCs) as a promising candidate for miniaturized energy storage components have undergone considerable theoretical and experimental investigations. Particularly, planar MSCs with a 2D architecture design have more attractive application prospects due to their flexible design and excellent electrochemical performance. However, the major drawbacks of MSCs are their intrinsically low energy density. For this reason, researchers have conducted much investigation to improve their energy density in order to promote their practical application. Herein, the recent development and progress of planar MSCs from the scope of the substrates, electrode materials, fabrication methods, electrochemical properties, and applications are discussed. Finally, the currently existing challenges and developments associated with planar MSCs are also discussed. All in all, planar MSCs have great application potential in various fields of electrochemical energy storage, self-powered wireless sensors, and stimuli-responsive and photoresponsive, alternating current line filtering.

Microsupercapacitors (MSCs) are integrated into microdevices or chip‐based systems to store energy and power the chip efficiently, as they present excellent performance capabilities including high power density, fast charge/discharge rate, and long cycle time. Providing sufficient surface area and high electric conductivity are effective ways to enhance ion diffusion and charge transportation in electrodes, which in turn leads to high performance behavior. Herein, the novel progress of on‐chip MSCs in the past few years ranging from active materials synthesis to high‐resolution fabrication techniques is summarized, and the strategies to enhance the performance of MSCs are focused upon. From conventional materials to nanocomposite hybrid structures, the main active materials for MSC electrodes and the related fabrication techniques are reviewed in detail according to their different electrochemical performance. It is concluded that hierarchical porous‐structured materials and high‐resolution fabrication processes are of great importance in constructing high‐performance devices, which also demonstrates the future developing direction of on‐chip energy devices. The new developments of fabrication technologies such as microfabrication, laser direct writing, and inkjet printing are also discussed to show their advantages in forming high‐performance electrodes.
