An electrochemical test sensor for detecting the concentration of an analyte in a fluid sample. The electrochemical test sensor includes a housing that has a first end and a second opposing end. The housing includes an opening at the first end to receive a fluid test sample. An electrode assembly includes a substrate, a working electrode, a counter electrode and a reagent. The substrate has a first surface and an opposing second surface. The working electrode is disposed on the first surface of the substrate, and the counter electrode is disposed on the second surface of the substrate. The electrode assembly is positioned within the housing to define a reaction channel. The electrochemical test sensor may be used with a removable lancet mechanism or integrated within a lancet mechanism to form one integral unit.

Electrochemical test sensor

An analyte sensor is provided that comprises a substrate which includes a semiconductor material. Embodiments may include a core of a conductive material, and a cladding of a semiconductor material, in which the cladding may form at least a portion of a conducting path for a working electrode of the analyte sensor. Method of manufacturing and using the analyte sensor are described, as are numerous other aspects.

Semiconductor based analyte sensors and methods

Integrated lancet/electrochemical test sensor assembly

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-elastic-resonance sensor. When the test strip is within the opening, the interrogation coil may utilize magneto-elastic-resonance technology to interrogate the magneto-elastic-resonance sensor and the pick-up coil may be used to sense a resultant oscillation frequency of the magneto-elastic-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.
