  • Patent number: 10533964
    Abstract: The invention relates to a method for analyzing the composition of a gaseous stream comprising at least two gaseous components, one of which is methane; and to a sensor array and a gas sensor comprising such sensor array. The method comprises contacting the gaseous mixture with a sensor, wherein the sensor comprises a sensor array comprising at least two sensor elements, wherein each of said sensor elements comprises a transducer coated with a coating comprising a polymeric material having at least one property that is responsive to one or more of said gaseous components when exposed thereto, wherein said sensor elements differ at least in the composition of the coating, providing an energy input to said transducers that is converted to output signals based on said property, and obtaining said output signals.

  • Publication number: 20170138862
    Abstract: The invention relates to an optical waveguide having a Fibre Bragg Grating, which waveguide is provided with a coating having a nanoporous sensor material, the sensor unit further having an optical detection unit for detecting a change in an optical property of the waveguide, wherein the grating is present in the core of the waveguide and the coating at least substantially surrounds the grating. The coating is expandable or shrinkable under the influence of the chemical substance, thereby causing a change in axial strain in the grating when the sensor material is exposed to the chemical substance, which change is detectible by a optical detection unit.
