NEDO, NIMS, Aisin Seiki, and Ibaraki University have developed a high-performance thermoelectric material composed exclusively of abundant chemical elements (iron, aluminum, and silicon) capable of generating sufficient electricity when subjected to a low-temperature heat source to drive IoT devices and allow them to perform BLE communications. The group then used this material to develop a novel thermoelectric module. We plan to promote widespread use of this technology, which may effectively supply electricity to IoT devices.
