? 2022 Elsevier LtdA novel transient heat flux sensor (THFS) was developed to measure the heat flux of an explosive driven shock tube. The working principle of the THFS is based on the transverse Seebeck effect (TSE) of a single crystal Bi2Te3. The sensor has a rise time of 51 μs and sensitivity of up to 69.8 μV/(kW/m2), with no signal amplifier required for the transient high heat flux test. This sensor allows for highly time-resolved measurements of heat flux in the explosion field, thereby supporting the study of the thermal damage effect of an explosion.
