Abstract:Thermoelectric (TE) technology is regarded as alternative and environmentally friendly technology for harvesting and recovering heat which is directly converted into electrical energy using thermoelectric generators (TEG). Conversely, Peltier coolers and heaters are utilized to convert electrical energy into heat energy for cooling and heating purposes The main challenge lying behind the TE technology is the low efficiency of these devices mainly due to low figure of merit (ZT) of the materials used in making them as well as improper setting of the TE systems. The objective of this work is to carry out a comprehensive review of TE technology encompassing the materials, applications, modelling techniques and performance improvement. The paper has covered a wide range of topics related to TE technology subject area including the output power conditioning techniques. The review reveals some important critical aspects regarding TE device application and performance improvement. It is observed that the intensified research into TE technology has led to an outstanding increase in ZT, rendering the use TE devices in diversified application a reality. Not only does the TE material research and TE device geometrical adjustment contributed to TE device performance improvement, but also the use of advanced TE mathematical models which have facilitated appropriate segmentation TE modules using different materials and design of integrated TE devices. TE devices are observed to have booming applications in cooling, heating, electric power generation as well as hybrid applications. With the generation of electric energy using TEG, not only does the waste heat provide heat source but also other energy sources like solar, geothermal, biomass, infra-red radiation have gained increased utilization in TE based systems.However, the main challenge remains in striking the balance between the conflicting parameters; ZT and power factor, when designing and optimizing advanced TE materials.Hence more research is necessary to overcome this and other challenge so that the performance TE device can be improved further.

“…Unlike solar and wind energy, an imponderable amount of thermal energy from the industrial field is released as waste heat [46]. Thus, energy harvesting from this waste heat has also been widely researched in fields of transportation [47][48][49][50] and industry [51,52]. Where there is thermal energy, TEG can be a sustainable power supply for WSNs.…”

With the increasing demand for Internet of Things (IoT) with integrated wireless sensor networks (WSNs), sustainable power supply and management have become important issues to be addressed. Thermal energy in forms of waste heat or metabolic heat is a promising source for reliably supplying power to electronic devices; for instance, thermoelectric power generators are widely being researched as they are able to convert thermal energy into electricity. This paper specifically looks over the application of thermoelectricity as a sustainable power source for IoT including WSNs. Also, we discuss a few thermoelectric systems capable of operating electronic skin (e-skin) sensors despite their low output power from body heat. For a more accurate analysis on body heat harvesting, models of the human thermoregulatory system have been investigated. In addition, some clever designs of heat sinks that can be integrated with thermoelectric systems have also been introduced. For their power management, the integration with a DC-DC converter is addressed to boost its low output voltage to a more usable level.

Yaşanan hızlı nüfus artışı, sanayileşme oranının yükselmesi ve teknolojideki gelişmeler enerjiye duyulan ihtiyacı günden güne arttırmaktadır. Dünya genelinde birçok endüstriyel tesise ait enerji tüketiminin yaklaşık olarak dörtte birinin atmosfere atılan atık gazlar ile kaybolduğu varsayılmaktadır. Çok büyük miktarda olan bu kaybın tekrar kazanılması geri kazanım sistemleri ile mümkün hale gelmektedir. Bu çalışmada atık ısı geri kazanım sistemleri üzerine yapılmış olan daha önceki çalışmalar sınıflandırılarak incelenmiştir. Ayrıca örnek bir vaka çalışması yapılarak doğalgaz yakıtlı bir kazan için baca gazı ısı geri kazanım potansiyeli araştırılmış, atık baca gazındaki ısıdan yararlanmak amacıyla ısı geri kazanım sistemi (reküperatör) tasarlanmıştır. Tasarlanan sistem için; enerji analizleri, ısı transfer analizleri ve ekonomik analizler yapılmış, sistemin 15 yıllık ekonomik ömrü boyunca sağlayacağı yakıt tasarrufu, Net Bugünkü Değer Metodu ile 1.121.410,23 TL olarak hesaplanmıştır.
