Beschreibung
Zusammenfassung:	Described herein are methods for forming resistive heaters and force sensing elements on a flexible substrate, and devices that include these elements to provide a force responsive conductive heater, such as a seat heater in a vehicle. The methods include printing a conductive ink on a flexible substrate that is heated to 30oC to 90oC before and/or during the printing process and curing the substrate to produce a conductive pattern thereon. The conductive inks generally include a particle-fee metal-complex composition formulated from at least one metal complex and a solvent, and optionally, a conductive filler material. L'invention concerne des procédés pour former des dispositifs de chauffage résistifs et des éléments de détection de force sur un substrat flexible, et des dispositifs qui comprennent ces éléments pour fournir un dispositif de chauffage conducteur réagissant à une force, tel qu'un dispositif de chauffage de siège dans un véhicule. Les procédés comprennent l'impression d'une encre conductrice sur un substrat flexible qui est chauffé à une température de 30oC à 90oC avant et/ou pendant le processus d'impression, et le durcissement du substrat pour produire un motif conducteur sur celui-ci. Les encres conductrices comprennent généralement une composition de complexe métallique exempte de particules formulée à partir d'au moins un complexe métallique et d'un solvant, et éventuellement, d'un matériau de charge conducteur.
