摘要： A field effect transistor (20) for chemical sensing, comprising an electrically conducting and chemically sensitive channel (2) extending between drain (5) and source (6) electrodes. A gate electrode (7) is separated from the channel (2) by a gap (10) through which a chemical to be sensed can reach the channel (2) which comprises a continuous monocrystalline graphene layer (2a) arranged on an electrically insulating graphene layer substrate (1 ). The graphene layer (2a) extends between and is electrically connected to the source electrode (5) and the drain electrode (6). The substrate supports the graphene layer, allowing it to stay 2-dimensional and continuous, and enables it to be provided on a well defined surface, and be produced and added to the transistor as a separate part. This is beneficial for reproducibility and reduces the risk of damage to the graphene layer during production and after. Low detection limits with low variability between individual transistors are also enabled. There is also provided a chemical sensor (30) using the transistor (20) and a method for providing the transistor (20).

摘要： Method for the testing of catalysers of combustion engines, where a gas sensor is placed in the exhausts after the catalyser which is sensitive to some substances normally burnable for the catalyser, for instance a thin oil. While the engine runs, momentarily a suitable amount of this substance is fed to the inlet of the engine, so that the gas sensor indicates the presence of the substance in the exhaust gases and so indicates the correct functioning of the catalyser system.

摘要： The present invention relates to a method for detecting particles and a particle sensor arrangement. More specifically, the present invention relates to a method and arrangement for detecting particles in a gas flow, e.g. from a diesel combustion engine. The method comprises the steps of; forcing a particle build up on a sensor element of a particle sensor arrangement by regulating the sensor element to a second temperature; wherein the second temperature is lower than a first temperature, the first temperature being the gas flow temperature. Additionally is the particle build up detected at the sensor element by means of a detector. The present invention provides for an accurate method and arrangement to detect and thereby measure particles present in a gas flow, e.g. from a combustion engine.

摘要： Sensor for the detection of unburnt hydrocarbons, and including a catalytic surface at which a chemical reaction may take place in the presence of the catalyst, where the reaction influences a semiconductor device that in this way can deliver a signal, at which the sensor for the elimination of other disturbing sources to which the sensor is sensitive are detected by means of one or several additional essentially similar sensors where however the actual sensor function has been blocked so that these additional sensors or parts deliver signals corresponding to possible disturbances.

摘要： The present invention is a gas sensitive semiconductor device suitable for forming arrays having one or more elements containing at least two layers disposed on a semiconductor substrate, the layers offering better long term stability and faster response compared to elements with only one layer. The layer in contact with the gas to be detected is catalytically active while the other layers do not have to be catalytic but provide changes in the electric field outside the semiconductor in the presence of the gas to be detected. The sensing portion may be operated up to about 1000 DEG C and is therefore of interest for gas sensitive devices based on e.g. silicon carbide or diamond capable of operation at higher temperatures than that for silicon based devices.
