Abstract
The warming article contains a heating element and a sensing system. The sensing system has a first sensor element being a temperature dependent variable resistor and a second sensor element having at least two resistors in series and corresponding jumpers for one or more resistors in the second sensor element. The first sensor element is linear and flexible and the second sensor element is used to adjust the total sensor resistance to a fixed value at a particular temperature.
