Historically, fire disasters have killed numerous human lives, and caused tremendous property loss. Fire warning systems play a vital role in predicting fire risks, and are strongly desired to effectively prevent the disaster occurrence and significantly reduce the loss. Among the developed fire warning systems, thermoelectrics (TEs) and thermocells (TECs)-based fire warning materials are extremely important and indispensable in future research, owing to their unique capability of direct conversion between heat and electricity. Here, we present this review of the recent progress of TEs and TECs in fire warning field. Firstly, a brief introduction of existing fire warning systems is provided, including the mechanisms and features of various types. Then, the mechanisms of electronic TE (eTE), ionic TE (iTE) and TEC are elucidated. Next, the basic principles for the material preparation and device fabrication are discussed in their dimension sequence. Subsequently, some important advances or examples of TE fire warnings are highlighted in details. Finally, the challenges and prospects are outlooked.
从历史上看，火灾灾难夺走了无数人的生命，并造成了巨大的财产损失。火灾预警系统在预测火灾风险方面发挥着至关重要的作用，人们强烈希望能够有效地预防灾难发生并显著减少损失。在已开发的火灾预警系统中，基于热电材料（TEs）和热电池（TECs）的火灾预警材料在未来研究中极为重要且不可或缺，这是由于它们具有热与电直接转换的独特能力。在此，我们对热电材料和热电池在火灾预警领域的最新进展进行综述。首先，简要介绍现有的火灾预警系统，包括各类系统的机制和特点。然后，阐明电子热电材料（eTE）、离子热电材料（iTE）和热电池的机制。接下来，按照尺寸顺序讨论材料制备和器件制造的基本原理。随后，详细突出了热电火灾预警的一些重要进展或实例。最后，展望挑战与前景。
