Abstract.
• Thermoelectric (TE) has emerged as a promising alternative green technology due to its distinct advantages. TE offers a potential application in the direct conversion of waste-heat into electrical energy, where it is unnecessary to consider the cost of the thermal energy. The principle of TE is the Seebeck effect, the potential energy generated where the temperature gradient occurred. TE has a wide range of applications in textiles, households, automobiles, and wearable power generators.
• In our research group, focus on wearable power generators; the body heat from the human is one of the sources to harvest energy, which produces electricity. Then the power generator design in the form of a textile, so-called wearable power generator (WPG). It is also made available in the form of curtain, tent, and umbrellas and therefore, it is useful not only for daily life applications but for special applications such as natural disasters. TE materials have prominent aspects like reliability, environmental benignity, and easy incorporation into existing technologies. They can be used as long-life power sources and provide a long-lasting solution to the ever-growing demand for implantable medical devices. This increasing demand for lightweight, highly flexible, stretchable, and washable presents critical challenges for the progress of WPG.
