Abstract
A variable resistance flexure sensor, and a system and method of controlling an appliance using a variable resistance flexure sensor are provided. The sensor can include a substrate having a flexible portion and a non-flexible portion. A plurality of electrically resistive elements, such as a first resistive element and a second resistive element, can be disposed on the substrate where at least one resistive element is exclusively within the non-flexible portion of the substrate and at least one resistive element is within the flexible portion of the substrate. The resistive element within the non-flexible portion of the substrate can act as a reference resistance for the flexure sensor and can be used as, or as part of, a biasing network for the electrically resistive element within the flexible portion of the substrate. The flexure sensor can be used within an appliance to detect various conditions such as temperature, moisture, etc.
