Abstract: This invention provides improved printed heaters for use in wearable garments. The improvement comprises replacing the single large area resistive material layer with a number of small patches of resistive material, i.e., replacing the single large area heater with a number of smaller individual heaters. Printing of the resistive material is facilitated since the area of each resistive material patch is greatly reduced. In addition, some embodiments enable the opportunity to provide a breathable heater.

Abstract: This invention provides a method for using a polymer thick film conductor composition to form an electrical conductor in an electrical circuit, the method subjecting the deposited thick film conductor composition to lamination. The invention also provides a method for reducing the resistance of an electrical conductor formed from a polymer thick film conductor composition, the method comprising the step of subjecting the electrical conductor to lamination. The invention further provides devices containing electrical conductors made by these methods.

Abstract: The invention is directed to a polymer thick film silver composition comprising: (a) conductive silver flakes and (b) an organic medium consisting of (1) acrylic organic polymeric binder; and (2) organic solvent. The composition may be processed at a time and energy sufficient to remove all solvent. The invention is further directed to novel method(s) of circuitry formation on printed wiring board constructions.

Abstract: Disclosed is the use of carbon layers as barriers to prevent silver migration in circuitry crossovers, either over a bottom circuitry layer and/or beneath subsequent circuit layers.
