Abstract
A fluid sensor includes a support structure having a top main surface region; a thermal emitter on the top main surface region of the support structure; a thermal radiation detector on the top main surface region of the support structure; and a waveguide structure having a first and a second waveguide section on the top main surface region of the support structure. The first waveguide section guides a first portion of the thermal radiation to the thermal radiation detector and the second waveguide section guides a second portion of the thermal radiation to the thermal radiation detector. The waveguide structure enables an interaction of an evanescence field of the guided first and/or second portion of the thermal radiation with a surrounding fluid.
