Abstract:

A test meter system for testing a characteristic of a fluid, the test meter system including a test meter having a housing with an opening adapted to accept a test strip, an interrogation coil within the housing, a pick-up coil within the housing, and a test strip including at least one magneto-electronic-resonance sensor. When the test strip is within the opening, the interrogation coil may utilize magneto-electronic-resonance technology to interrogate the magneto-electronic-resonance sensor and the pick-up coil may be used to sense a resultant oscillation frequency of the magneto-electronic-resonance sensor, the resultant oscillation frequency associated with the characteristic. The test strip may include a plurality of sensors. The sensors may be coated with a coating sensitive to a characteristic of the fluid, where the interrogation reveals information about the fluid characteristic.
