“…To produce high quality implantable/wearable devices, tremendous efforts [262][263][264][303][304][305][306][307][308] have been made to increase the output power or power density [20] (W cm −2 ) of TEGs in order to obtain sufficient power supply and also to reduce the size and weight of the TEGs. Benefiting from the development of highly efficient TE materials and advanced microfabrication technologies, [180,186,240,306,[309][310][311][312][313][314][315][316][317] niche applications of implantable/ wearable devices powered by miniaturized TEGs with extended lifetimes become very promising.…”

Thermoelectric (TE) materials have the capability of converting heat into electricity, which can improve fuel efficiency, as well as providing robust alternative energy supply in multiple applications by collecting wasted heat, and therefore, assisting in finding new energy solutions. In order to construct high performance TE devices, superior TE materials have to be targeted via various strategies. The development of high performance TE devices can broaden the market of TE application and eventually boost the enthusiasm of TE material research. This review focuses on major novel strategies to achieve high‐performance TE materials and their applications. Manipulating the carrier concentration and band structures of materials are effective in optimizing the electrical transport properties, while nanostructure engineering and defect engineering can greatly reduce the thermal conductivity approaching the amorphous limit. Currently, TE devices are utilized to generate power in remote missions, solar–thermal systems, implantable or/wearable devices, the automotive industry, and many other fields; they are also serving as temperature sensors and controllers or even gas sensors. The future tendency is to synergistically optimize and integrate all the effective factors to further improve the TE performance, so that highly efficient TE materials and devices can be more beneficial to daily lives.

“…Elemental properties we considered [labeled as X i in eqs. (1)(2)(3)(4)(5)(6)(7)(8)] fall into three categories: (i) location of the element in the periodic table, (ii) fundamental properties of the elements, (iii) experimentally measured properties of pure elements in their crystalline states. Properties within category (i), the location of elements in the periodic table, include atomic number, period, and group, and whether or not the element can be classified as an alkali, alkaline earth, transition metal, post-transition metal, metalloid, lanthanide, actinide, nonmetal, halogen, or noble gas.…”

The regression model-based tool is developed for predicting the Seebeck coefficient of crystalline materials in the temperature range from 300 K to 1000 K. The tool accounts for the single crystal versus polycrystalline nature of the compound, the production method, and properties of the constituent elements in the chemical formula. We introduce new descriptive features of crystalline materials relevant for the prediction the Seebeck coefficient. To address off-stoichiometry in materials, the predictive tool is trained on a mix of stoichiometric and nonstoichiometric materials. The tool is implemented into a web application (http://info.eecs.northwestern.edu/SeebeckCoefficientPredictor) to assist field scientists in the discovery of novel thermoelectric materials. © 2017 Wiley Periodicals, Inc.

As we are advancing our world to smart living, a critical challenge is increasingly pressing -increased energy demand. While we need mega power supplies for running data centers and other emerging applications, we also need instant small-scale power supply for trillions of electronics that we are using and will use in the age of Internet of Things (IoT) and Internet of Everything (IoE). Such power supplies must meet some parallel demands: sufficient energy supply in reliable, safe and affordable manner. In that regard, thermoelectric generators emerge as important renewable energy source with great potential to take advantage of the widely-abundant and normally-wasted thermal energy. Thanks to the advancements of nano-engineered materials, thermoelectric generators' (TEG) performance and feasibility are gradually improving. However, still innovative engineering solutions are scarce to sufficiently take the TEG performance and functionalities beyond the status-quo. Opportunities exist to integrate them with emerging fields and technologies such as wearable electronics, bio-integrated systems, cybernetics and others. This review will mainly focus on unorthodox but effective engineering solutions to notch up the overall performance of TEGs and broadening their application base. First, nanotechnology's influence in TEGs' development will be introduced, followed by a discussion on how the introduction of mechanically reconfigurable devices can shape up the emerging spectrum of novel TEG technologies. The technology-driven age we are currently in, have brought great advantages to establish a more comfortable and smarter living and it is leading the way for an even faster-growing development in all areas of science and engineering, but at the same time it brings an incredibly fast growing demand for energy. Current and future energy consumption mandate the need for alternative energy sources, with reduced environmental impact. Readily available solar and wind energies have lead the way as alternative energy sources to environmentally challenging fossil fuels.1 Moreover, thanks to more recent developments in thermoelectric (TE) materials and devices, the possibility of making a better use of the widely abundant and normally wasted thermal energy, has becoming a popular and feasible alternative.2 More importantly, thermal waste has become a very important and environmentallyfriendly source of otherwise wasted energy.3,4 There has been already an important set of studies covering the mechanism involved during the conversion from thermal to electric energy. [5][6][7][8] Such studies have been the starting point to develop and optimize novel TE materials with the resourceful aid of uprising nanotechnologies. 9,10 In this review, we will first shortly introduce some important basic concepts and relations about thermoelectrics, as well as some of the current efforts to use nanotechnologies and nano-materials to improve performance and viability. Next, we will focus on identifying innovative devices, novel engineering approach...
