Abstract
A fluid sensor detects a target fluid and comprises thermal radiation emitters emitting a broadband thermal radiation, a waveguide structure guiding the thermal radiation comprising an evanescent field component, an optical filter structure coupled to the waveguide structure to provide a filtered thermal radiation having a center wavelength, a thermal radiation detector configured to provide a detector output signal based on a radiation strength of the filtered thermal radiation, and an actuation device for connecting the plurality of thermal radiation emitters with a power source such that the plurality of thermal radiation emitters has an operating temperature between 400 to 1300 K.
