    • In an embodiment, an oxygen sensor comprises a giant magnetoresistance device (10), and a magnetic field generator (14, 14a, 14b) arranged to generate a magnetic field (12, 12a, 12b) overlapping the giant magnetoresistance device and an examination region (20). A component (Bx) of the magnetic field detected by the giant magnetoresistance device is dependent upon an oxygen concentration in the examination region. In an embodiment, a chip (40) includes one or more electrically conductive traces (14a, 14b) disposed on or in the chip and a giant magnetoresistance device (10) disposed on or in the chip such that electrical current flowing in the trace or traces generates a magnetic field (12a, 12b) that overlaps the magnetic field sensor, said magnetic field being perturbed (Bx) by ambient oxygen (24) such that a signal output by the magnetic field sensor indicates ambient oxygen concentration.
    • 在一个实施例中,氧传感器包括巨磁电阻装置(10)和布置成产生与巨磁电阻装置重叠的磁场(12,12a,12b)的磁场发生器(14,14a,14b)和检查区 (20)。 由巨磁电阻装置检测的磁场的分量(Bx)取决于检查区域中的氧浓度。 在一个实施例中,芯片(40)包括设置在芯片上或芯片中的一个或多个导电迹线(14a,14b)和设置在芯片上或芯片上的巨磁电阻器件(10),使得流过迹线或 轨迹产生与磁场传感器重叠的磁场(12a,12b),所述磁场被环境氧(24)扰动(Bx),使得由磁场传感器输出的信号表示环境氧浓度。
