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 invention relates to a sensor device(100) and a method for the determination of the amount of target particles(1) at a contact surface(112) adjacent to a sample chamber(2). Target particles(1) in the sample chamber are detected by a sensor element(SE) and at least one corresponding sensor-signal (s, s') is provided. An evaluation unit(EU) then determines the amount of target particles(1) in a first zone(Z1) immediately at the contracts surface(112) and a second zone(Z2) a distance(z) away from the contact surface based on this sensor-signal. In an optical measurement approach, frustrated total internal reflection taking place under different operating conditions (e.g. wavelength, angle of incidenceq) may be used to extract information about the first and second zones(Z1, Z2). In a magnetic measurement approach, different magnetic excitation fields may be used to excite magnetic target particles differently inthe first and second zone(Z2). Moreover, the temporalcourse of a sensor-signal(s, s') can be evaluated, particularly with respect to stochastic movements ofthe target particles(1).

摘要： A detection system (100, 150) for qualitative or quantitative detection of a magnetic field property of a modulated magnetic field is described. The modulated magnetic field may e.g. stem from an adjacent electrical current (Iadj) or magnetic particles. The detection system (100, 150) comprises at least one magneto resistive sensor element (102), a current controller (104) for providing a sensing current (Isense) flowing through the magnetic sensor element (102) and a controlling means (108). The controlling means (108) is adapted for deriving at a first frequency f1 a temperature-related parameter of the at least one magneto resistive sensor. The controlling means (108) furthermore is adapted for deriving a qualitative or quantitative characteristic of the adjacent electrical current (Iadj) or magnetic particles, taking into account the derived temperature-related parameter. This second frequency (f1) is different from the first frequency (f1}). The invention also relates to a corresponding method.

摘要： The invention relates to a magnetic sensor device for the determination of magnetized particles (3) which comprises a magnetic field generator (1, 1') (e.g. a conductor wire) that is driven with an excitation current (II) of a first frequency (f1), and a magnetic sensor element (2) (e.g. a GMR resistance), that is driven with a sensor current (I2) of a second frequency (f2) for generating measurement signals (UGMR). A preprocessed signal (uf) is then generated from the measurement signal (UGMR) that comprises a predetermined frequency (Δf), and an evaluation unit (10) separates from this preprocessed signal a spurious component that does not depend on the presence of magnetized particles (3) in the sample chamber. The spurious component (UQ) may particularly be caused by self-magnetization (H2) of the magnetic sensor element (2) in combination with parasitic (capacitive or inductive) cross-talk. Furthermore, an unknown, variable phase-shift (φSP) in the preprocessed signal (uf) may be determined by varying the ratio between the spurious component and a particle-dependent target component. This variation may for example be achieved if, in an optimization stage (OS), the excitation current (I1) is conducted through a bypass resistor (R, R') and/or if an additional capacitor is introduced between the magnetic field generator and the magnetic sensor element. The determined phase shift can then be used to adjust the phase of a demodulation signal (udem) such that the spurious component is suppressed.

摘要： The invention relates to a microelectronic device (100) with means for the determination of the wetting grade of a sensitive surface (22) that lies adjacent to a sample chamber (1) with a sample fluid. In a particular embodiment, the device may be a magnetic sensor device comprising magnetic excitation wires (11, 13) for the generation of magnetic fields (B) in the sample chamber and a GMR sensor (12) for sensing reaction fields (B') generated by magnetized particles (2). A detector module (30) can optionally be adapted to measure the resistance of conductors (11, 12, 13) which depends, via the dissipation of heat generated by electrical currents, on the wetting grade of the sensitive surface (22). In another embodiment, the capacitance of conductors is measured, which is affected at the sensitive surface by the presence of gas bubbles (4).
