Graphene

Approximately 52% of primary energy is lost as waste heat, most of which is low-temperature waste heat below 100 °C that is unsuitable for thermoelectric conversion. In this study, aiming to utilize low-temperature waste heat, we measured the electromotive force generated at the graphene–fluid interface in a temperature-controlled chamber to investigate its temperature dependence. The results revealed that the electromotive force increased with increasing temperature difference between graphene and the fluid and was always generated in the direction of fluid flow, regardless of the direction of heat transfer.
