Eutectic gallium–indium (EGaIn), a liquid metal with a melting point close to or below room temperature, has attracted extensive attention in recent years due to its excellent properties such as fluidity, high conductivity, thermal conductivity, stretchability, self-healing capability, biocompatibility, and recyclability. These features of EGaIn can be adjusted by changing the experimental condition, and various composite materials with extended properties can be further obtained by mixing EGaIn with other materials. In this review, not only the are unique properties of EGaIn introduced, but also the working principles for the EGaIn-based devices are illustrated and the developments of EGaIn-related techniques are summarized. The applications of EGaIn in various fields, such as flexible electronics (sensors, antennas, electronic circuits), molecular electronics (molecular memory, opto-electronic switches, or reconfigurable junctions), energy catalysis (heat management, motors, generators, batteries), biomedical science (drug delivery, tumor therapy, bioimaging and neural interfaces) are reviewed. Finally, a critical discussion of the main challenges for the development of EGaIn-based techniques are discussed, and the potential applications in new fields are prospected.

智能共晶镓-铟：从属性到应用
共晶镓-铟（EGaIn）是一种熔点接近或低于室温的液态金属，因其具有流动性、高导电性、导热性、可拉伸性、自愈性等优异性能，近年来受到广泛关注、生物相容性和可回收性。EGaIn的这些特性可以通过改变实验条件进行调整，将EGaIn与其他材料混合可以进一步得到具有扩展性能的各种复合材料。在这篇综述中，不仅介绍了 EGaIn 的独特特性，还阐述了基于 EGaIn 的器件的工作原理，并总结了 EGaIn 相关技术的发展。EGaIn在柔性电子（传感器、天线、电子电路）等各个领域的应用，审查了分子电子学（分子存储器、光电开关或可重构结）、能量催化（热管理、电机、发电机、电池）、生物医学科学（药物输送、肿瘤治疗、生物成像和神经接口）。最后，对开发基于 EGaIn 的技术所面临的主要挑战进行了批判性讨论，并对新领域的潜在应用进行了展望。
