Method of making flexible electronic circuitry

Abstract

Stitchable electrical components have flexible, conductive leads and are encased, at least partially, in sealed packages. Conductive threads, yarns, or fiber bundles are patterned onto a flexible substrate (e.g., a textile panel). To form a circuit, the component leads are conductively stitched, spot welded, or otherwise joined to a textile panel so as to form connections between at least some of the stitched leads so as to form an electrical circuit. Alternatively, leads stitched into or otherwise joined to a textile pattern may be welded or otherwise permanently joined to flexible or non-flexible component leads to form a circuit. Multiple panels of circuitry so formed may then be physically and electrically joined at various locations by a combination of stitching, welding, and/or other joining means, preferably with interposed insulating layers, to form a multilayer flexible circuit.
