摘要： The present invention is directed to flexible conductive articles (600) that include a printed circuit (650) and a stretchable or non-stretchable substrate (610). In some embodiments, the substrate has a printed circuit on both sides. The printed circuit contains N therein a porous synthetic polymer membrane (660) and an electrically conductive trace (670) as well as a non-conducive region (640). The electrically conductive trace is imbibed or otherwise incorporated into the porous synthetic polymer membrane. In some embodiments, the synthetic polymer membrane is microporous. The printed circuit may be discontinuously bonded to the stretchable or non-stretchable substrate by adhesive dots (620). The printed circuits may be integrated into garments, such as smart apparel or other wearable technology.

摘要： The present disclosure is flexible and stretchable conductive articles that include a printed circuit and a stretchable substrate. The printed circuit contains an electrically conductive trace. The electrically conductive trace may be positioned on the surface of or be imbibed into the pores through the thickness of a synthetic polymer membrane. The synthetic polymer membrane is compressed in the x-y direction such that buckling of the membrane occurs in the z-direction. Additionally, the synthetic polymer membrane may be porous or non-porous. In some embodiments, the synthetic polymer membrane is microporous. The printed circuit may be discontinuously bonded to the stretchable substrate. Advantageously, the flexible, conductive articles retain conductive performance over a range of stretch. In some embodiments, the conductive articles have negligible resistance change when stretched up to 50% strain. The printed circuits may be integrated into garments, such as smart apparel or other wearable technology.

摘要： The present invention is directed to flexible printed circuits for dermal applications that include a synthetic polymer membrane 702 and at least one electrically conductive trace 705. In an alternative embodiment, the electrically conductive trace is located on both sides of the microporous synthetic polymer membrane. The electrically conductive trace may be located on the surface of or be imbibed into the pores and through the thickness of a microporous synthetic polymer membrane. The flexible printed circuits may be electrically coupled to an electronic component to form a flexible printed circuit board and adhered to the skin 701 by a dermally acceptable adhesive. The flexible printed circuit or the flexible printed circuit board may be coupled to an electronic module 703 to form a hybrid flexible printed circuit board. The flexible printed circuit, flexible printed circuit board, and hybrid flexible printed circuit board achieve a balance of comfort, flexibility, and durability for on-skin use.

摘要： A thin, biocompatible, high-strength, composite material is disclosed that is suitable for use in various implanted configurations. In one aspect, the composite material maintains flexibility in high-cycle flexural applications, making it particularly applicable to high-flex implants such as a prosthetic heart valve leaflet. The composite material includes a porous expanded fluoropolymer membrane and an elastomer, wherein the elastomer is present in the pores of the porous expanded fluoropolymer.
