Concept of TE sheet for heat-flow sensing based on the LSSE.

The LSSE-based TE sheet consists of a metallic film and a magnetic (ferro- or ferrimagnetic) film formed on a flexible substrate. When a heat flux q flows through the TE sheet, a spin current js is induced and injected from the ferrite film into the metallic film by the LSSE. Then the js is finally converted into an electric voltage V as a result of the inverse spin Hall effect (ISHE) in the metallic film. The thin and simple bilayer structure of the TE sheet allows us to design novel heat-flow sensors with low thermal resistance and a flexible shape.
