Heat-flow sensing with a bent TE sheet.

(a) TE voltage V from a flat Pt/Ni0.2Zn0.3Fe2.5O4/polyimide sample as a function of an external magnetic field H measured when the heat flux q was applied across the sample over a 20 × 20-mm2 area. (b) H dependence of the TE voltage V from a Pt/Ni0.2Zn0.3Fe2.5O4/polyimide sample that was bent with a radius of curvature r = 17 mm, when the heat flux q was applied across the sample over a 20 × 20-mm2 area. (c) Heat-flow sensitivity V/q as a function of curvature r−1, indicating that V/q is almost independent of r−1.
