Abstract
An apparatus for sensing a physical attribute is shown, that includes a first track (511) defining a first electrode on a substrate (512), a second track (513) defining a second electrode on said substrate and an active film (514) in cooperation with a first sensor portion (516) of the first electrode and a second sensor portion (517) of the second electrode. The second electrode includes a first extended portion (517) to establish a first additional resistance not cooperating with the active film.

An apparatus for sensing a physical attribute, comprising:
- a first track defining a first electrode on a substrate;
- a second track defining a second electrode on said substrate;
- and
- an active film comprising a variable resistance material in cooperation with a first sensor portion of said first electrode and a second sensor portion of said second electrode, wherein:
- said second electrode includes a first extended portion to establish a first additional resistance not cooperating with said active film;
- and
- said first sensor portion, said second sensor portion and said first extended portion comprise the same conductive material.
A method of constructing an apparatus for sensing a physical attribute, comprising the steps of:
- defining a first electrode on a substrate;
- further defining a second electrode on said substrate;
- arranging an active film comprising a variable resistance material to cooperate with a first sensor portion of said first electrode and a second sensor portion of said second electrode;
- and
- establishing a first additional resistance in an extended portion of said first electrode;
- wherein said first sensor portion, said second sensor portion and said first extended portion comprise the same conductive material.
A method of sensing a physical attribute, comprising the steps of:
- exposing a sensor portion of cooperating electrodes to said physical attribute, in which variable current flows through said cooperating electrodes;
- and
- measuring a voltage with respect to a reference resistance,
- wherein said reference resistance is established as a first additional resistance in one of said cooperating electrodes, said sensor portion and said first additional resistance comprise the same conductive material.
