摘要:
Es wird ein Flussdetektor beschrieben, der zwei Gehäuseteile (1, 2) besitzt, zwischen denen ein Halbleiterchip (3) mit integriertem Flussmesser angeordnet ist. In einem der Gehäuseteile ist eine Verbindungsöffnung (11) vorgesehen, in der mindestens ein Metallstift (10) angeordnet ist. Zur Abdichtung zwischen dem Metallstift (10) und dem Gehäuseteil wird eine aushärtende Füllmasse (12) verwendet. Diese Konstruktion erlaubt eine gute Abdichtung und eine einfache Herstellung des Bauteils.

A gas sensor comprises a set of one or more sensor cells (SC) and a substrate (1). Each sensor cell (SC) of the set comprises a sensitive film (42) built from a sensitive material (4) covering an area of the substrate (1). One or more elevated structures (2) are manufactured in or around said area for preventing the sensitive material (4) to expand when being applied thereto.
摘要:
A method for manufacturing gas sensors with a metal oxide layer as sensitive layer is described using the steps of providing a substrate and sensitive and/or electrode material and building a sensitive structure and/or an electrode contacting the sensitive structure by contactless dispensing the sensitive and/or electrode material onto the substrate through a capillary, wherein the contactless dispensing step includes an additional focussing step after the sensitive material has exited the capillary by generating an electrical force field or a fluid-dynamic force field at a location between the capillary and the substrate, thus generating structures of a characteristic length in the range of 30 microns to 10 nm.

A chemical sensor (11) of a portable electronic device (1) is authenticated by reading a cryptographic sensor identifier from a memory of the chemical sensor and transmitting sensor-related data from the portable electronic device to a remote evaluation unit (6), the sensor-related data comprising the cryptographic sensor identifier. The sensor-related data may be transmitted in encrypted form. The sensor-related data may be complemented with a device identifier for the portable electronic device.
摘要:
In a method for calibrating a portable first electronic device (1) comprising a first chemical sensor, a determination is carried out whether the first electronic device is located near a second electronic device comprising a second chemical sensor. If this is the case and if optionally other criteria are fulfilled, readings of the first and second chemical sensor are compared. Subject to the comparison, calibration values for the first chemical sensor are derived.
