Abstract:
Methods, systems, and apparatus for high-resolution patterning of various substrates with functional materials, including nanomaterials. A technique of preparing a patterned substrate in a high-resolution mold for stick and transfer process is disclosed with promotes integrity of the high-resolution pattern onto the substrate. One example of a substrate is an adhesive tape. The transferred pattern(s) are scalable and can be implemented in different fabrication processes. One example is a roll-to-roll processes. In one embodiment, the transferred pattern comprises nanomaterials and the substrate comprises a flexible substrate for use in flexible and conformal assemblies for a wide variety of applications including, but not limited to, electrical-based sensors on non-planar inanimate surfaces, plant body surface, or human or animal skin.
