Abstract: Methods for fabricating printed devices and monitoring one or more performance characteristics of the printed devices during their fabrication in a high-speed process. Such a method includes developing a physics-based model of at least a first component of the printed devices, fabricating the printed devices with the high-speed process using fabrication steps that comprise depositing the first components, acquiring a physical characteristic of a plurality of the first components of a plurality of the printed devices following the depositing of the first components, predicting a performance characteristic of the printed devices based on the physics-based model of the first component and the physical characteristic acquired of the plurality of the first components; and then modifying at least one of the fabrication steps performed during the fabricating of a subsequently-fabricated group of the printed devices to adjust the performance characteristic of the subsequently-fabricated group of the printed devices.

Abstract: Processes and machines suitable for producing polymer films, and films produced thereby. Lead zirconate titanate (PZT) particles and electrically conductive nanoparticles are combined in a liquid polymer precursor matrix and aligned along nanocolumns in a thickness direction of the polymer precursor matrix by subjecting the PZT and nanoparticles to a uniform electric field, after which the polymer precursor matrix is solidified to form a piezoelectric polymer composite film. The PZT and nanoparticles are subjected to the uniform electric field for a duration sufficient to promote sensitivity and/or energy harvesting properties of the piezoelectric polymer composite film.

Abstract: A roll-to-roll manufacturing machine suitable for processing and producing polymer films that contain nanostructures, including but not limited to multifunctional polymer films. The machine applies a liquid polymer on a substrate to form a liquid polymer film, at least partially embeds nanostructures into the liquid polymer film, melt casts a layer of a molten polymer on the liquid polymer film to produce a thin polymer film, organizes the nanostructures in a thickness direction of the thin polymer film comprising applying an electric field to the thin polymer film, aligns the nanostructures in the thin polymer film by simultaneously subjecting the thin polymer film to heat and a field that aligns the nanostructures, and solidifies the thin polymer film to freeze the nanostructures along nanocolumns in a thickness direction of a solidified polymer film resulting therefrom.
