Abstract
Described are systems, methods, devices, apparatuses, and materials suitable for fabricating flexible microcavity structures and integrating flexible microcavity structures into multi-functional flexible hybrid electronics and electronic components, as well as systems, devices, apparatuses, methods, and computer program products for screen-printing flexible microcavity structures and for integrating flexible microcavity structures into multi-functional flexible hybrid electronics.
Claims20
A method comprising:
- providing a substrate comprising a planar substrate material and a first electrode material coupled to at least a portion of a top surface of the planar substrate material;
- disposing one or more volumes of an ink through one or more patterned screens onto a top surface of the substrate;
- at least partially curing the one or more volumes of the ink to form a plurality of microstructures on the top surface of the substrate, wherein the top surface of the substrate and the plurality of microstructures define one or more microcavities;
- and
- disposing a capping film over at least a portion of the plurality of microstructures to encapsulate at least a portion of the one or more microcavities between the top surface of the substrate and a bottom surface of the capping film.

A method comprising:
- disposing a first patterned screen above a substrate;
- screen-printing a first portion of a resin ink through the first patterned screen and onto at least a portion of a top surface of the substrate;
- after screen-printing the first portion of the resin ink through the first patterned screen, disposing a retractable ultraviolet light emitting diodes between the first patterned screen and the substrate;
- emitting ultraviolet light from the ultraviolet light emitting diodes to at least partially cure the first portion of the resin ink screen-printed onto the top surface of the substrate;
- retracting the retractable ultraviolet light emitting diodes;
- disposing a second patterned screen above the substrate;
- screen-printing a second portion of the resin ink through the second patterned screen and onto one or both of at least a portion of the top surface of the substrate or at least a portion of a top surface of the first portion of the resin ink previously screen-printed onto at least a portion of the top surface of the substrate;
- after screen-printing the second portion of the resin ink through the second patterned screen, disposing the retractable ultraviolet light emitting diodes between the second patterned screen and the substrate;
- and
- emitting ultraviolet light from the ultraviolet light emitting diodes to at least partially cure the second portion of the resin ink to form a plurality of microstructures, wherein the top surface of the substrate and the plurality of microstructures define a plurality of microcavities therebetween.
