Abstract:
A method of forming a self-supported electronic device, including depositing a sacrificial layer on a first surface substrate, wherein the sacrificial layer is substantially soluble in a first solvent. At least one device layer is deposited in a desired pattern on top of the sacrificial layer. The at least one device layer is substantially insoluble in the at least one device layer. The sacrificial layer is at least partially dissolved in the first solvent to release at least a portion of the first device layer from the substrate. The at least one device layer removed from the substrate forms a self-supported electronic device, which is a thin film electronic device having at least a portion thereof that is not supported by a material carrier.

Abstract:
The present invention relates to a flexible antenna that can harvest energy for short-range wireless communication such as near-field communication. The flexible antenna comprises a plurality of metal loops arranged in a concentric manner and disposed on a flexible base substrate. In some embodiments the flexible antenna can be stretchable. In some embodiments, the flexible antenna can be conformal. A flexible device comprising a chip or an integrated circuit electrically connected to the antenna can be used to perform one or more desirable functions (including user authentication, mobile payments, and/or location tracking) The flexible device can adhere to a surface such as the skin of a user.

Abstract:
A conductive trace design is described that minimizes the possibility of crack initiation and propagation in conductive traces during bending. The conductive trace design has a winding trace pattern that is more resistant to the formation of cracks at high stress points in the conductive traces. The conductive trace design includes a cap that helps ensure electrical connection of the conductive trace even though one or more cracks may begin to form in the conductive portion of the conductive trace.
