“…Such limitations could be overcome by WSN systems powered by stand-alone, microscale thermoelectric generators, which obtain their power by energy harvesting. Millimeter scale TEGs such as those produced by Kim et al 80 are reported to be able to generate 270 μW of electrical power which is sufficient to broadcast data in a wireless sensor node. 80 Huang et al 79 reported a very effective TEG powered building WSN demonstrator which worked with temperature differences of 3-8 o C. Later Kuchle and Love 81 employed thermoelectric sensing loops and realised a WSN system which could monitor directly temperature and magnetic field strength via an integrated Hall monitor.…”

“…As can be seen from the figure, it has been used to drive miscellaneous devices, ranging from satellites to tiny biomedical devices. [ 31–39 ] An imperative feature of this harvester is that it consistently harnesses energy from a range of heat sources, such as human body heat, heat exchangers, automobile radiators, solar radiation, radioactive isotopes (generates heat from the natural radioactive decay of plutonium‐238), and transforms them into electrical energy without requiring any moving elements and maintenance, which makes it more reliable. A TEG is a solid‐state device that converts thermal energy (i.e., temperature gradient, Δ T ) into electric potential through Seebeck effect phenomenon.…”

Energy harvesters (EHs) are widely used to transform ambient energy sources into electrical energy, and have tremendous potential to power wearables electronics and biomedical devices by eliminating, or at least increasing, the battery life. Nevertheless, the use of EHs for a specific application depends on various aspects including the form of energy source, the structural configuration of the device, and the properties of materials. This paper presents a comprehensive review of the classification of EHs, notably thermoelectric generators (TEGs), triboelectric nanogenerators (TENGs), and piezoelectric generators (PEGs) that allows a wide variety of devices to be operated. The EHs are discussed in terms of their operating principles, optimization factors, state‐of‐the‐art materials, and device structure, that directly influence their operational efficiency. Besides, the breakthrough performance of each of the EHs listed above is highlighted. From the review and analysis, the maximum output power density of 9.2 mW cm−2, 50 mW cm−2, and 64.9 µW cm−2, respectively, are obtained from the TEG, TENG, and PEG, respectively. Furthermore, recent applications relevant to a specific EH and their output performance, are also enlightened. Eventually, the essential outcomes and future direction from this review are discussed and encapsulated.

“…In recent years, with the development of many polymer-based thermoelectric composites, flexible thermoelectric devices can not only be self-energized by thermal energy in the environment but can also monitor changes in the environment, such as human body temperature and pressure. [162][163][164][165][166][167] Seo et al 165 developed a dual output sensor based on the structural design of thermoelectric materials (SDTM) which was designed to monitor fluid temperature and dynamics. When the temperature of the working fluid is 312 K (DT = 14 K), the power density is 42 mW cm À2 .…”
