This paper reports a flexible thermoelectric generator (TEG) that provides efficient conversion of body heat to electrical energy. The device relies on a low thermal conductivity aerogel–silicone composite that secures and thermally isolates the individual semiconductor elements that are connected in series using stretchable eutectic gallium-indium (EGaIn) liquid metal interconnects. The composite consists of aerogel particulates mixed into polydimethylsiloxane (PDMS) providing as much as 50% reduction in the thermal conductivity of the silicone elastomer. Worn on the wrist, the flexible TEGs present output power density figures approaching 35 μWcm − 2 at an air velocity of 1.2 ms − 1 , equivalent to walking speed. The results suggest that these flexible TEGs can serve as the main energy source for low-power wearable electronics.}, number={1}, journal={NPJ FLEXIBLE ELECTRONICS}, author={Padmanabhan Ramesh, Viswanath and Sargolzaeiaval, Yasaman and Neumann, Taylor and Misra, Veena and Vashaee, Daryoosh and Dickey, Michael D. and Ozturk, Mehmet C.}, year={2021}, month={Mar} }

We fabricated samples with different GnP and EGaIn concentrations and measured their thermal conductivity using the steady-state absolute technique. The results show that the thermal conductivity of the elastomer can be enhanced up to 5.6X when both GNP and EGaIn are included in the elastomer. Without EGaIn, the enhancement is limited to 4.4X. The results suggest that EGaIn inclusion did not change the viscosity of the uncured material significantly at any GnP loading level. We also observed that addition of just EGaIn to PDMS did not have a significant impact on the material's stiffness while lowering its ultimate tensile strength by a factor of 2X and the maximum elongation at the break point by a factor of 1.6X. On the other hand, it was demonstrated that GnP addition to pure PDMS or EGaIn doped PDMS made the elastomer stiffer and less tear resistant with lower elongation at the break point.}, number={6}, journal={ECS JOURNAL OF SOLID STATE SCIENCE AND TECHNOLOGY}, author={Sargolzaeiaval, Yasaman and Ramesh, Viswanath Padmanabhan and Neumann, Taylor V. and Miles, Rebecca and Dickey, Michael D. and Ozturk, Mehmet C.}, year={2019}, month={Jun}, pages={P357–P362} }

With further growth and commercialization of thermoelectric technology beyond niche applications, other factors such as materials availability, toxicity, cost, recyclability, thermal stability, chemical and mechanical properties, and ease of fabrication become important for making viable technologies. Several silicide alloys were identified that have the potential to fulfill these requirements. These materials are of interest due to their abundancy in earth’s crust (e.g., silicon), non-toxicity, and good physical and chemical properties. In this paper, an overview of the silicide thermoelectrics from traditional alloys to advanced material structures is presented. In addition, some of the most effective approaches as well as fundamental physical concepts for designing and developing efficient thermoelectric materials are presented and future perspectives are discussed.}, number={5}, journal={JAPANESE JOURNAL OF APPLIED PHYSICS}, author={Nozariasbmarz, Amin and Agarwal, Aditi and Coutant, Zachary A. and Hall, Michael J. and Liu, Jie and Liu, Runze and Malhotra, Abhishek and Norouzzadeh, Payam and Oeztuerk, Mehmet C. and Ramesh, Viswanath P. and et al.}, year={2017}, month={May} }
