Thesemethods have been used in producing everyday smart printed electronics such as conformalantennas (planner and non-planar antennas), sensors, actuators, and solar cells createdon flexible and rigid substrates. The performance of printed electronics strongly dependson printing techniques and printing resolution that enhance their electrical and mechanicalproperties. In this dissertation, 3D and surface printing techniques were used to enhancethe performance of printed electronics devices fabricated on rigid and flexible substrates.First, fused deposition modeling (FDM) technique was used to study the effectof 3D printed heterogeneous substrates on radio frequency response of microstrip patchantennas. Microstrip patch antennas created on acrylonitrile butadiene styrene (ABS) substratesthat were designed by 3D CAD design software (SOLIDWORKS) with dimension50mm x 50mm x 5mm and fabricated with different machine infill densities 25%, 50%,and 75% using FDM 3D printer. Then, 3D X-ray microscope was used to measure theactual volume fraction and construct equivalent simulations for series and parallel equivalentdielectrics constant. The patch antennas were tested for resonant frequency usinga vector network analyzer (VNA) combined with ANSYS-HFSS simulation that was developedbased on the permittivity anisotropy in 3D printed heterogeneous substrates toestimate the bulk permittivity of ABS material and study the effect of varying the dielectricconstant in lateral and thickness direction. Also, microstrip patch antenna with dimension30mm x 25mm, was modeled on polydimethylsiloxane (PDMS) substrate with the samedimension of ABS substrate and analyzed for resonant frequency using Ansoft HFSS andCOMSOL Multiphysics software. Then, COMSOL Multi-physics software was used tostudy the behavior of the microstrip patch antenna under different values of compressionand bending loads to check the feasibility of using the microstrip patch antenna as a passivesensor to detect the strain in the structure wirelessly. Second, piezoelectrical drop ondemand (DOD) inkjet printing was used to print uniform and even high conductive nanosilverink on rigid and flexible substrates. For surface printing, Jetlab 4xl was used to printlines of high conductive nanosilver ink (UTDAg) on semicrystalline polyether ether ketone(PEEK) substrate using fly mode printing with burst. Then, optimal bipolar waveform wasgenerated at proper jetting parameters to generate ideal droplet in term of velocity, size,and uniformity. The ideal droplet was ejected at different drop spacing and stage velocityto print uniform and even lines. Physical and adhesion characteristics of the printed lineswere performed by optical microscopy, scanning electron microscopy, surface profilometry,and soak tests. Also, the effect of high stage velocity printing on the spread behaviorof ejected droplet with different droplet spacing on Kapton substrate was studied by printinglines using two bipolar waveforms. The resistance of printed lines were measured atdifferent curing temperature. Finally, the effect of driving waveforms at different jettingparameters on the size and velocity of generated droplet was investigated using smartink(nanosilver ink) produced by Genes’Ink. A new method was developed to measure the sizeof the generated droplet and recognize weather the droplet has a spherical or an ellipticalshape by using Python programming and the result compared with Aphelion imagingsoftware. Finally, lines printed at three waveform voltages on PEEK and glass substrates. 2020-08-24 English text Wright State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=wright1598253714624332 http://rave.ohiolink.edu/etdc/view?acc_num=wright1598253714624332 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
