Abstract
A fluid sensor includes a housing structure forming a cavity for an IR emitter for emitting an IR radiation in the cavity, wherein the IR radiation has a center wavelength for providing an interaction of the IR radiation with the target fluid resulting in a temperature change in the cavity or in the housing structure, which effects a mechanical pulse in the housing structure, and an inertial detection sensor mechanically coupled to the housing structure for sensing the mechanical pulse in the housing structure.
