 le crystals have the potential to produce an electric signal perpendicular
  to an applied temperature gradient. This effect is known as the Transvers
 e Seebeck Effect (TSE) and can be leveraged to build thermoelectric device
 s compatible with harsh environments. In this work\, we report on the deve
 lopment and characterization of a heat flux sensor using the TSE in single
  crystal rhenium. The sensor features a simple\, robust construction\, and
  is fabricated with ceramics and alloys compatible with temperatures excee
 ding 1000 °C.  The heat flux sensor is characterized from room temperatur
 e to 500 °C using a new temperature-controlled calibration facility devel
 oped at the University of Maryland. The sensor exhibits a voltage response
  that is both linear with respect to the applied heat flux and augmented a
 s the conditions become more challenging. The sensor’s responsivity remai
 ns stable after long term exposure to temperatures as high as 1000 °C\, d
 emonstrating good compatibility of the sensing platform with harsh environ
 ments. These results showcase the unique use case of the TSE in refractory
  metals for robust thermoelectric devices and highlight the potential perf
 ormance that can be achieved by TSE-based sensors in applications such as 
 space exploration\, energy production\, and high-speed flight.
