A ceramic printing ink is provided that is suitable for application using an inkjet printing process to produce a coating on glass ceramics. The ink includes a glassy material of glass particles and pigment particles. The glass particles are present in a ratio of total weight to the pigment particles of at least 1.5 and less than 19. The glass particles have an equivalent diameter d.sub.90 ranging from at least 0.5 μm to at most 5 μm. The ink has an effective coefficient of linear thermal expansion, α.sub.20-300,eff, in a range from 6.5*10.sup.−6/K to 11*10.sup.−6/K.

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 30° C. to 90° C. before and/or during the printing process and curing the substrate to produce a conductive pattern thereon. The conductive inks generally include a particle-free metal-complex composition formulated from at least one metal complex and a solvent, and optionally, a conductive filler material.
