power-dense, owing to their tuneable nanostructures. Hence, smaller TENGs are better suited for small form-factor applications like wearable electronics, internet of things (IoT) devices, and self-powered sensors. However, the higher complexity and cost of TENGs than TEGs inhibit their widespread adoption. This review appraises the latest advances in TENG materials, design, and fabrication in optimizing the performance of TENGs, making TENGs more viable for real-world applications. More precisely, this work examines how nanostructure engineering, nanomaterial compositing, and post-synthesis treatment approaches have enhanced the TE properties of common and promising TE materials, including tellurides, selenides, metal oxides, metal alloys, silicon, carbon nanomaterials, and organic compounds. Given that the TE material is a key component in TENGs, this review highlights how to optimize other vital parameters, including the TENG configuration, contact interface, form factor, heat sink use, and folded shape for specific applications. Lastly, critical attributes of TENGs used in wearable electronics, sensors, implantable electronics, solar energy conversion, and waste heat recovery are analyzed.

“…1 These well-known toxic and expensive elements cause major constraints on the widespread implementation of thermoelectrics, 1 and as such, the development of new and abundant thermoelectric materials is essential to replace expensive and toxic elements. [1][2][3] Such new materials should also exhibit improved or at least comparable thermoelectric performance to that of well-known "state-of-the-art" compounds for them to become widely used in device fabrication. [4][5][6][7] The thermoelectric efficiency, also known as the "gure of merit" (zT) of a material, depends on the electrical conductivity (s), the Seebeck coefficient (S), and the thermal conductivity (k).…”
