Abstract: A system and method is provided for creating a structure including a vasculature network. A film deposition device is configured to dispense droplets onto a surface of a substrate to form a curable fugitive pre-patterned liquid film on the surface of the substrate. An electrohydrodynamic film patterning (EHD-FP) device has a patterned electrode structure formed to generate an electric field and to subject the film on the surface of the substrate to the electric field. The film thereby being formed by the EHD-FP into patterned features in response to being subjected to the electric field. Then a casting system is configured to cover the patterned features in an epoxy to form patterned structures, wherein the patterned structures comprise a fugitive vasculature structure.

Abstract: A coating mechanism disposes a liquid (e.g., polymer) thin film onto a conveyor surface (e.g., roller or belt) that is moved by a suitable motor to convey the thin film into a precisely controlled gap (or nip) region where applied potentials generate an electric field that causes the liquid to undergo Electrohydrodynamic (EHD) patterning deformation, whereby the liquid forms patterned micro-scale features. A curing mechanism (e.g., a UV laser) is used to solidify (e.g., cross-link) the patterned liquid features inside or immediately after exiting the gap region, thereby forming micro-scale patterned structures that are either connected by an intervening web as part of a sheet, or separated into discrete micro-scale structures. Nanostructures (e.g., nanotubes or nanowires) disposed in the liquid become vertically oriented during the EHD patterning process. Segmented electrodes and patterned charges are utilized to provide digital patterning control.

Abstract: A deposition system has a reservoir of a material to be deposited, the material having fibers, a print head having a mixer to generate a mixed flow of the materials having fibers, a flow focusing section arranged to cause short fibers to align inside the print head, and an outlet of the print head to allow the material to be deposited on a substrate, and a controller to actuate the print head to control an orientation of the print head relative to a substrate to cause longer fibers to align external to the print head. A deposition system includes a reservoir of a material to be deposited, the material having fibers, a print head connected to the reservoir of material by a conduit, the print head having an exit nozzle and an actuator, the actuator to control the orientation of the exit nozzle relative to a substrate.

Abstract: The disclosed spray deposition systems and methods use spray charging and discharging techniques to assist with digital deposition of spray droplets on a substrate. For example, the disclosed systems and methods have a charging system that generates spray droplets from a spray generator and charges the droplets. Focusing electrodes help to collimate the droplets into a tight droplet stream and, optionally, steering electrodes help direct the tight droplet stream. A charge removal system neutralizes or removes the charge from the droplets, either during the deposition of the droplets on a substrate or after the droplets have been deposited on a substrate.

Abstract: A liquid thin film is disposed on a conveyor surface (e.g., a roller or belt) that moves the thin film into a precisely controlled gap (or nip) region in which the liquid thin film is subjected to an electric field that causes the liquid to undergo electrohydrodynamic (EHD) patterning deformation, whereby portions of the liquid thin film form patterned liquid features having a micro-scale patterned shape. A curing mechanism (e.g., a UV laser) is used to solidify (e.g., in the case of polymer thin films, cross-link) the patterned liquid inside or immediately after exiting the gap region. The patterned structures are either connected by an intervening web as part of a polymer sheet, or separated into discreet micro-scale structures. Nanostructures (e.g., nanotubes or nanowires) disposed in the polymer become vertically oriented during the EHD patterning process. Segmented electrodes and patterned charges are utilized to provide digital patterning control.
