需要一个连续的地下管道监测系统，以避免能源浪费或管道爆炸，并尽量减少对环境的负面影响。热电驱动的物联网（IoT）传感器可能是一个很有前途的解决方案，因为热电发电机提供可靠的电源，可以通过管道表面吸收废热。共形热电发生器（cTEG）适用于管道应用，但目前的研究主要集中在收集人体热量，这是不适合管道系统，因为不同的热路径。这种cTEG设备的独特设计提供了清除中低品位废热的能力，这是地下管道系统最常见的废热源。所提出的器件制造方法将体TE元件与柔性印刷电路板相结合，以最大化功率输出并最小化成本。在50 °C的温差下，集成了四对p-n结的cTEG的输出功率密度为1.26 mW/m2，比现有文献报道的值高2倍。这项研究提供了一个潜在的途径，使用TEG作为能源，以成本效益的方式为地下管道监测系统提供动力，用于真实的应用。
A continuous underground pipeline monitoring system is needed to avoid energy waste or pipeline explosions and minimize the negative environmental impact. Thermoelectric-powered Internet of things (IoT) sensors can be a promising solution due to reliable power sources supplied by thermoelectric generators to scavenge the wasted heat through the pipeline surface. Conformal thermoelectric generators (cTEGs) are suitable for pipeline applications; however, the current study is mainly focused on harvesting body heat, which is not suitable for piping systems because of the different thermal path. Here we designed and fabricated a film-based cTEG on a roll-to-roll manufacturing platform using an electrothermal model to achieve an optimized device structure and performance. The unique design of this cTEG device provides the capability of scavenging mid- to low-grade waste heat, which is the most common wasted heat source for underground pipeline systems. The proposed device fabrication method combines bulk TE elements with a flexible printed circuit board to maximize the power output and minimize the cost. The resulting power output density of a cTEG integrated with four pairs of p–n junctions is 1.26 mW/m2at a temperature difference of 50 °C, which is 2 times higher than the value reported in the current literature. This study provides a potential pathway for using TEGs as energy sources for powering underground pipeline monitoring systems in a cost-effective way for real applications.
