“…For example, a power density of 5.26Wcm is achieved with a 500°C temperature difference between hot and cold sides [13]. Under the ambient temperature variation, the maximum output power can reach 0.6 mW, which corresponds to a power density of 37.5μWcm [14]. The power density is proportional to ΔT (where T is the temperature difference) and hence the use of thermoelectric generators in aircraft has been limited to powering wireless sensor nodes, which can be used for structural health monitoring [15,16].…”

This paper gives an overview of energy harvesting techniques for generating electrical power from ambient energy such as vibration, heat and light. Typically, the electrical power is used to energise sensing systems and their associated communication channels, which are often wireless in nature. The amount of electrical power generated is in the region of tens of micro watts to hundreds of milli watts. The use of assets in service generally results in some form of ageing as a consequence of elevated temperature, chemical degradation, absorption of energetic radiation, mechanical wear, etc. and, as a consequence, as time progresses, the probability of failure increases. In some situations, it may be acceptable on grounds of cost and consequent impact to accept periodic failure and asset replacement while, in many others, such a strategy is unacceptable such that regular maintenance, condition assessment, life prediction and pre-emptive replacement must be carried out. A clear example of this is in connection with mass transport, notably aviation, where the impact of catastrophic failure can be dire. Condition assessment may be achieved through periodic examination or by continuous monitoring but, in many circumstances, the latter approach has much to recommend it. This commonly involves the measurement of relevant parameters and the subsequent export of data for decision making. Such systems require sensors, data logging, communications hardware, etc. plus a source of energy. A broad overview of energy scavenging techniques is presented, along with an assessment of useful materials for each mode of harvesting.

“…Thus, based on the obtained model, a geothermal TEG (GTEG) system was performed as a computational study, where the GTEG system provided annual electric output of 681.5 MWh. Moreover, Tuoi et al [113] conducted research that shows the significant potential of TEG integrated with PCM, especially with the rise of the new era of the Internet of Things (IoT). Such potential is illustrated more in research held [114] that studied a complete self-powered wireless sensor nodes (WSNs) system.…”

Electricity plays a significant role in daily life and is the main component of countless applications. Thus, ongoing research is necessary to improve the existing approaches, or find new approaches, to enhancing power generation. The thermoelectric generator (TEG) is among the notable and widespread technologies used to produce electricity, and converts waste energy into electrical energy using the Seebeck effect. Due to the Seebeck effect, temperature change can be turned into electrical energy; hence, a TEG can be applied whenever there is a temperature difference. The present paper presents the theoretical background of the TEG, in addition to a comprehensive review of the TEG and its implementation in various fields. This paper also sheds light on the new technologies of the TEG and their related challenges. Notably, it was found that the TEG is efficient in hybrid heat recovery systems, such as the phase change material (PCM), heat pipe (HP), and proton exchange membrane (PEM), and the efficiency of the TEG has increased due to a set of improvements in the TEG’s materials. Moreover, results show that the TEG technology has been frequently applied in recent years, and all of the investigated papers agree that the TEG is a promising technology in power generation and heat recovery systems.

“…The considerable growth of research studies in energy-harvesting technologies, such as solar energy harvesting [1], RF power harvesting [2], thermoelectricgenerator-based electrolyte [3], thermoelectric-generator-based solid thermoelectric materials [4], associated with the Internet of Things (IoT) leads to more demands in the development of the high performance of a micro-thermoelectric generator (TEG). Micro-TEG keeps a role as a charger to the rechargeable battery of IoT sensing systems or even replaces the battery if micro-TEG with high performance is employed.…”

Micro-thermoelectric generator (TEG) possesses a great potential for powering wireless Internet of Things (IoT) sensing systems due to its capability of harvesting thermal energy into usable electricity. Herein, this work reviews the progress in recent studies on the micro-TEG, including material synthesis, device fabrication, and application demonstration. Thermoelectric materials are synthesized by the electrochemical deposition method. Three kinds of high-performance thermoelectric materials, including thick bulk-like thermoelectric material, Pt nanoparticles embedded in a thermoelectric material, and Ni-doped thermoelectric material, are presented. Besides the material synthesis, novel fabrication methods for micro-TEG can also help increase its output power and power density significantly. Two fabrication processes, micro/nano fabrication technology and assembly technology, are investigated to produce high-performance micro-TEG. Moreover, the fabircated micro-TEG as a power source for portable and wearable electronic devices has been demonstrated successfully.
