    摘要: The invention relates to a microelectronic sensor device for manipulating a sample in an exchangeable carrier (111), for example for optically detecting target particles (1) in a sample liquid that is provided in a sample chamber (2) of the carrier (111). The microelectronic sensor device comprises a number of n>1 magnetic field generators (141-143), e.g. electromagnetic coils, with which magnetic fields can be generated in a target region (110). A control unit (150) is provided that can determine and evaluate the mutual coupling or the self-inductance of the magnetic field generators and/or signals from magnetic field sensors attached to the carrier with respect to the presence and/or state of a carrier (111) in the target region (110). In this way, the control unit (150) can for example detect if the carrier (111) is correctly positioned in the sensor device and/or where a magnetically interactive substance (1, 120) is located.

    摘要: The present invention provides a magnetic sensor device comprising a plurality of magnetic sensor elements having a sensitive direction. At least one of the magnetic sensor elements (43) is provided with a flux-guide (44) for concentrating onto the sensor element in its sensitive direction a magnetic field applied to the magnetic sensor device. The applied magnetic field is thus bent into the sensitive direction of the magnetic sensor element by the flux-guide. In that way, the field strength and/or orientation of the applied magnetic field can be measured in the absence of magnetic particles. This may be used for, for example, calibration of magnetic sensor devices.

    摘要: The invention relates to a magnetic sensor device comprising an excitation wire for the generation of an alternating magnetic excitation field (Bi) and a GMR sensor (12) for sensing reaction fields (B2) generated by magnetized particles (2) in reaction to the excitation fields. Moreover, it comprises a compensator (15) for the generation of a magnetic compensation field (B3) that adaptively cancels predetermined spectral components of all magnetic fields (B2, B3) which lie in the sensitive direction of the magnetic sensor element (12). Measurements of the GMR sensor (12) are thus made robust against gain variations of the sensor.
