Abstract
In an embodiment, an oxygen sensor comprises a giant magnetoresistance device (), and a magnetic field generator () arranged to generate a magnetic field () overlapping the giant magnetoresistance device and an examination region (). A component (B) 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 () includes one or more electrically conductive traces () disposed on or in the chip and a giant magnetoresistance device () disposed on or in the chip such that electrical current flowing in the trace or traces generates a magnetic field () that overlaps the magnetic field sensor, said magnetic field being perturbed (B) by ambient oxygen () such that a signal output by the magnetic field sensor indicates ambient oxygen concentration.
