Subject matter herein can include identifying a biochemical test strip assembly electrically, such as using the same test circuitry as can be used to perform an electrochemical measurement, without requiring use of optical techniques. The identification can include using information about a measured susceptance of an identification feature included as a portion of the test strip assembly. The identification can be used by test circuitry to select test parameters or calibration values, or to select an appropriate test protocol for the type of test strip coupled to the test circuitry. The identification can be used by the test circuitry to validate or reject a test strip assembly, such as to inhibit use of test strips that fail meet one or more specified criteria.

Susceptance measurement for identifying biochemical sensors

A low-cost system comprising a pattern arranged to encode information and a decoder for decoding the information encoded in the pattern is described. In particular, the mechanism employs a capacitive sensing technique. Electrodes are arranged (or stimulated, during operation) to each generate an electric field, and sense disturbances on the electric field caused by the pattern when the pattern is positioned over the electrodes. The spatial arrangement of the pattern allows information to be encoded on a strip or surface and decoded by capacitive sensors arranged to detect disturbances caused by possible patterns. The resulting solution is cheaper and less complex than optical solutions, e.g., barcodes and optical barcode readers. The mechanism may be used in a glucose meter for encoding and decoding an identifier for distinguishing batches of glucose meter test strips.
