| Abstract Scope |
There is an urgent need to develop technologies which can autonomously power IoT sensors and devices, such as thermoelectric thin films [1]. We have developed original materials in sulfides, skutterudites, Heuslers [2], and with collaborators, promising thermoelectric thin films have been fabricated from related materials [3]. In addition to latest developments of these, I will also present advancements made in thin film thermal conductivity measurements, enabling site selective measurements and separation of the interfacial thermal resistance [3,4], together with applicative considerations for power generation modules.
