Abstract
An electronic resistor user interface comprises flexible conductive materials and a flexible variably resistive element capable of exhibiting a change in electrical resistance on mechanical deformation and is characterised by textile-form electrodes (10,12), a textile form variably resistive element (14) and textile-form members (16) connective to external circuitry.
Claims17
A variable resistance user-interface comprising:
- at least two textile-form flexible conductive electrode layers, including a first textile-form flexible conductive electrode layer and a second textile-form flexible conductive electrode layer;
- at least two textile-form conductive linking members, including a first textile-form conductive linking member and a second textile-form conductive linking member;
- and
- a textile-form variably resistive element capable of exhibiting a change in electrical resistance upon mechanical deformation,
- wherein the textile-form variably resistive element is formed as a coating applied to the first textile-form flexible conductive electrode layer;
- wherein the first textile-form flexible conductive electrode layer is connected to the first textile-form conductive linking member, which is in turn connective to external circuitry;
- wherein the second textile-form flexible conductive electrode layer is positioned adjacent the textile-form variably resistive element;
- wherein the second textile-form flexible conductive electrode layer is connected to the second textile-form conductive linking member, which is in turn connective to the external circuitry;
- and
- wherein the textile-form variably resistive element is positioned between the first textile-form flexible conductive electrode layer and the second textile-form flexible conductive electrode layer.
