Certain crystallographic configurations of anisotropic single-crystal materials yield electrical signals both parallel and perpendicular to an applied steady-state heat flux. This effect is known as the Transverse Seebeck Effect and has the potential to significantly progress the state of the art in heat flux measurement technologies. We report on the use of single crystal Antimony prismatic structures to demonstrate the efficacy of the Transverse Seebeck Effect in unconventional heat flux sensor arrangements. A prototype heat flux sensor was constructed using a single Antimony sensing element and revealed a linear relationship between the applied temperature gradient and the measured perpendicular voltage. Measurements of the principal Seebeck coefficient tensor components in single crystal Antimony specimens accompanied with computational simulations reinforced the validity of the prototype sensor configuration. We are advancing towards the integration of multiple Antimony transducers into a single package to demonstrate the scalability of Transverse Seebeck Effect-based devices, as multiple sensing elements can be connected in series to amplify the measured electrical signal for a given heat flux.
