Abstract
A flexible printed circuit, sometimes referred to as a flexible membrane circuit, is screen printed onto one surface of a tightly woven polyester or nylon taffeta fabric. The opposite side of the fabric is coated with a long life pressure sensitive adhesive, protected until use by a suitable release sheet, or coated with a long life heat activated adhesive also protected with a suitable release sheet. The adhesive side of the fabric is applied to the underside of upholstery fabric, for example, the underside of an automobile seat. This provides an economical and functionally effective means of providing complex circuitry for sensing the presence of a person on the seat and/or detecting the weight of such person, etc. Significant savings are realized over conventional circuit-forming techniques.
