Atomic Layer Thermopile (ALTP) heat-flux sensors stand out by its unique characteristics with regard to its temporal resolution. They have a linear characteristic over approximately 10 orders of magnitude and cover a frequency range up to 2 MHz.

The sensors were used in several applications and flow environments in the past:

• Internal combustion engines
• Shock tube investigations and ignition studies of fuels / propellants
• Wind tunnel dignostics  (subsonic  to hypersonic flow regime, plasma)
• Boundary layer transition studies
• Rotating Detonation Engines
• Surface temperature determination e.g. steel industry
• Heat transfer studies e.g. for gas turbine cooling

The experimental results were published in several internatinal peer-reviewed journals.
