Encoded biosensors and methods of manufacture and use thereof

An analyte test sensor, comprising:

• a non-conductive substrate;
• a primary resistive element on the non-conductive substrate having a predetermined configuration, the predetermined configuration having a first end connected with a first contact pad and a second end connected to a second contact pad;
• a secondary resistive element on the non-conductive substrate having a plurality of non-uniformly distributed taps, wherein one tap of the plurality of taps is connected to the primary resistive element at a predetermined location thereby being formed in a closed state and defining a unique resistive path through the primary resistive network and remaining taps of the plurality of taps being formed in an open state thereby being disconnected from the primary resistive network, wherein a portion of the secondary resistive element is connected with a secondary resistive element contact pad, and wherein each tap of the plurality of taps are associated with one of a plurality of predetermined resistance values, the plurality of predetermined resistance values having a non-linear distribution.

A method of forming a circuit on a biosensor test strip, the method comprising:

• forming a primary resistive element on a non-conductive substrate having a predetermined configuration including a first end and a second end;
• and
• forming a secondary resistive element on the non-conductive substrate having at least one of a plurality of taps connected to a predetermined connection location on the primary resistive element thereby defining a plurality of unique resistive paths through at least a portion of the primary resistive element, each of the plurality of taps having associated therewith a resistance falling within a respective one of a plurality of ranges of resistances, wherein each of the range of resistances are determined based on a non-linear distribution function.
