Since it was reported in 2014, laser-induced graphene (LIG) has received growing attention for its fast speed, non-mask, and low-cost customizable preparation, and has shown its potential in the fields of wearable electronics and biological sensors that require high flexibility and versatility. Laser-induced graphene has been successfully prepared on various substrates with contents from various carbon sources, e.g., from organic films, plants, textiles, and papers. This paper reviews the recent progress on the state-of-the-art preparations and applications of LIG including mechanical sensors, temperature and humidity sensors, electrochemical sensors, electrophysiological sensors, heaters, and actuators. The achievements of LIG based devices for detecting diverse bio-signal, serving as monitoring human motions, energy storage, and heaters are highlighted here, referring to the advantages of LIG in flexible designability, excellent electrical conductivity, and diverse choice of substrates. Finally, we provide some perspectives on the remaining challenges and opportunities of LIG.
自 2014 年被报道以来，激光诱导石墨烯（LIG）以其快速、无掩模、低成本的可定制制备而受到越来越多的关注，并在需要高灵活性和多功能性的可穿戴电子设备和生物传感器领域展示了其潜力。LIG 已成功地在各种具有不同碳源含量的基底上制备，例如有机薄膜、植物、纺织品和纸张。本文综述了 LIG 在机械传感器、温度和湿度传感器、电化学传感器、电生理传感器、加热器和致动器等方面的最新进展和应用。本文重点介绍了基于 LIG 的设备在检测各种生物信号、监测人体运动、能量存储和加热方面的成就，这得益于 LIG 在灵活设计、优异导电性和多种基底选择方面的优势。最后，我们对 LIG 面临的挑战和机遇提出了一些看法。
