    摘要: A method and apparatus for detecting a gas in electrical equipment by coupling a gas detection device to the electrical equipment is provided. The method includes providing an electro-magnetic source, positioning an electro-magnetic detector to receive light emitted from the electro-magnetic source, and positioning a membrane between the electro-magnetic source and the electro-magnetic detector, such that the electro-magnetic detector only receives light from the electro-magnetic source that has been transmitted through the membrane. The method also includes detecting at least one gas, such that detection of at least one gas includes preventing or allowing communication of the electro-magnetic source and the electro-magnetic detector, and emitting a signal, by the electro-magnetic detector, in response to the detection of the at least one gas.

    摘要: Herein are disclosed methods and devices for detecting the presence of an analyte. Such methods and devices may comprise an array comprising at least two sensing elements that differ in their response to an analyte of interest. The sensing elements each comprise at least an optically responsive layer that comprises at least a highly analyte-responsive sublayer. At least one sensing element of the array further contains a minimally analyte-responsive sublayer that comprises part of the thickness of the optically responsive layer. Methods of making and using such arrays of sensing elements are also disclosed.

    摘要: A gas sensor includes an in-fiber resonant wavelength device provided in a fiber core at a first location. The fiber propagates a sensing light and a power light. A layer of a material is attached to the fiber at the first location. The material is able to absorb the gas at a temperature dependent gas absorption rate. The power light is used to heat the material and increases the gas absorption rate, thereby increasing sensor performance, especially at low temperatures. Further, a method is described of flash heating the gas sensor to absorb more of the gas, allowing the sensor to cool, thereby locking in the gas content of the sensor material, and taking the difference between the starting and ending resonant wavelengths as an indication of the concentration of the gas in the ambient atmosphere.
