Abstract: Flexible electronic structure and methods for fabricating flexible electronic structures are provided. An example method includes applying a first layer to a substrate, creating a plurality of vias through the first layer to the substrate, and applying a second polymer layer to the first layer such that the second polymer forms anchors contacting at least a portion of the substrate. At least one electronic device layer is disposed on a portion of the second polymer layer. At least one trench is formed through the second polymer layer to expose at least a portion of the first layer. At least a portion of the first layer is removed by exposing the structure to a selective etchant to providing a flexible electronic structure that is in contact with the substrate. The electronic structure can be released from the substrate.

Abstract: A passive nanomagnet alignment method is described to self-align a membrane to another surface. The membrane and the surface each have a plurality of nanomagnets patterned on it, wherein the nanomagnets are magnetized based on an applied external magnetic field. The membrane is brought into close proximity and coarse alignment to the surface by a positioning mechanism (e.g., an actuation force), such that the nanomagnets on the membrane attract to and self-align with the nanomagnets on said surface based on the nanomagnet magnetizations.
