Concept of the STE coating. a, Conventional TE generation method based on the Seebeck effect. The TE device contains a number of thermocouples (TCs), electrically connected in series, to obtain reasonable output voltage. The TE device is usually attached externally to heat sources, which apply the temperature difference across it. b, STE coating based on the SSE. The STE coating exhibits a straightforward scaling: a larger film area leads to a larger TE output. Such a simple film structure can be directly coated onto heat sources with different shaped (curved or uneven) surfaces.
