    摘要: A portable electronic device (1) comprises a control device (201), a chemical sensor (226) that is sensitive to a chemical analyte, and an output device (230-236) coupled to the control device. The control device carries out a measurement with the chemical sensor. It determines whether the portable electronic device has been handled appropriately during the measurement. If the portable electronic device has not been handled appropriately, the control device operates the output device to present information to a user of the portable electronic device. The information may include instructions to handle the portable electronic device in a specific manner. Determination whether the portable electronic device has been handled appropriately may be based on one or more parameters measured by a second sensor (211-225) that is different from the chemical sensor (226).

    摘要: In a method for identifying an odour and/or gas, an odour and/or gas is measured with a portable electronic device comprising a chemical sensor (12), the chemical sensor (12) being sensitive to different analytes. A measurement tuple (mt) is supplied which measurement tuple (mt) comprises a set of tuple elements with each tuple element (mtx) of the set of tuple elements (mtx) providing a value measured by a dedicated cell of the chemical sensor and/or under a dedicated operating condition of the chemical sensor or of a cell of the chemical sensor. The measurement tuple (mt) is compared to one or more reference tuples (rt) with each reference tuple (rt) representing an odour and/or gas and comprising a set of tuple elements and an identifier (id) for the odour and/or gas represented by the reference tuple (rt). Each tuple element of the set of tuple elements of the reference tuple (rt) provides a value characteristic for being sensed by the dedicated cell of the chemical sensor and/or under the dedicated operating condition of the chemical sensor or of the cell of the chemical sensor in the presence of the odour and/or gas represented by the concerned reference tuple (rt). One or more odour and/or gas identifiers (id) are returned to the portable electronic device subject to a result of the comparison.

    摘要: A relative humidity (Φ) of the environment of a humidity sensor (1) is measured by the humidity sensor (1) twice at different temperatures (T). For both measurements, a corresponding value (V) based on a saturated vapour pressure at the subject temperature (T) is calculated. The two calculated values (V1, V2) derived are then evaluated. The evaluation result allows for a conclusion if the humidity sensor (1) may be impaired in its capabilities of measuring humidity.

    摘要: In a method for manufacturing a sensor chip a substrate (1) is thinned to less than 300 µm by removing material from the substrate (1) prior to etching holes for building vias (15) extending through the substrate (1) between a front side (11) of the substrate (1) and its back side (12). After etching, the holes (14) are filled to complete the vias (15). Before or after etching, a sensing element (2) and a stiffener (3) are arranged at the front side (11). The reduced thickness (d2) of the substrate (1) allows etching holes with smaller diameters than as can be achieved with the standard thickness of substrates (1).
