Abstract: An apparatus includes a breath sensor including a film configured to sense a variation in electrical impedance based on a moisture gradient and output the sensed variation as an output signal; and a controller configured to process the output signal from the breath sensor. The apparatus is configured to receive the output signal from the breath sensor and provide a signal in response thereto.

Abstract: An apparatus including first and second sensor elements, the first sensor element includes a first sensor material. The second sensor element includes a second sensor material. The first sensor material is configured such that an electrical property of the first sensor material is dependent upon the temperature of the environment in which the first and second sensor elements are located. The second sensor material is configured such that the same electrical property of the second sensor material is dependent upon the relative vapor pressure of a fluid in the environment in which the first and second sensor elements are located, the respective temperature and fluid relative vapor pressure dependencies of the first and second sensor materials allowing the temperature and fluid relative vapor pressure of the environment to be determined based on combined measurements of the electrical property of the first and second sensor materials in the environment.

Abstract: An apparatus including a first sensor including a sensing material that is sensitive to a first parameter and a second parameter, wherein sensitivity to the first parameter changes sensitivity to the second parameter. The sensitivity of the first sensor to one of the first and the second parameters may be controlled by maintaining, as a constant, the other of the first and the second parameters. The apparatus may include a second sensor sensitive to at least one of the first parameter and the second parameter. The first parameter may be deformation and the second parameter may be a concentration of a gaseous analyte such as, for example, humidity. The second sensor may include the sensing material that is sensitive to the first parameter and the second parameter.
