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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Oxygen concentration measurement with GMR","description":"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 g","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8542009","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
