Bridging the Length-scale Gap: Synthesizing Three-dimensional Ceramic Microlattices by Aerosol Jet Nanoparticle Printing: Bin Yuan1; Chunshan Hu1; Rahul Panat1; 1Carnegie Mellon University
    Three dimensional (3D) ceramic micro/mesoscale lattice structures are important for a wide range of technological applications. In spite of considerable progress in this area, the current processes suffer from control over dimensions at length scales below about a millimeter. In this research, we report an entirely new approach to synthesize complex 3D microengineered ceramic structures such as micro pillars and micro lattices by using Aerosol Jet (AJ) nanoprinting. Complex lattice structures of zinc-oxide with a minimum feature size of 30 um and having aspect ratios of up to 25:1 without any templating/support are demonstrated, thus filling an important gap in possible ceramic architectures. The structures show a shrinkage of 1-2% after sintering, leading to near-net-shape part fabrication. We demonstrate a device using AJ printed ceramic 3D structures where an electrochemical cell is used to detect Her2 breast cancer biomarkers by immobilizing antibodies on the rough and porous 3D ceramic surfaces.

Direct 4D Printing of Stretchable Supercapacitors Using Hybrid Composite Materials: Yihao Zhou1; Charles Parker2; Jeffrey Glass2; Pooran Joshi3; Amit Naskar3; Changyong Cao1; 1Michigan State University; 2Duke University; 3Oak Ridge National Laboratory
    Stretchable supercapacitors (SCs) have attracted significant attention in developing power-independent stretchable electronic systems due to their intrinsic energy storage function and unique mechanical properties. In this talk, we will present a facile method to fabricate arbitrary-shaped stretchable electrodes via direct 4D printing of conductive nanocomposite made of reduced graphene oxide (RGO), carbon nanotube (CNT), and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS). The electrode patterns of an arbitrary shape can be deposited onto prestretched substrates by aerosol jet printing, then self-organized origami (ridge) patterns are generated after releasing the substrates from holding stretchers due to the mismatched strains. The stretchable electrodes demonstrate superior mechanical robustness and stretchability without sacrificing its outstanding electrochemical performance. The proposed method paves avenues for scalable manufacturing of future energy-storage devices with controlled extensibility and high electrochemical performance.

Flexible Electric Energy Storage for Low-power Devices: By Liya Napollion1; Kwang Kim1; 1University of Nevada, Las Vegas
    Electroactive polymers (EAPs) are suitable materials for the growth of flexible and compact capacitors. Ionic polymer metal composites (IPMCs) are flexible, robust, small in size and shape, and can produce large macro bending deformation in response to small, applied voltages. These characteristics place the material an ideal candidate for replacing conventional capacitors. IPMC capacitor that consist of a thin strip can be fabricated to any planar shapes and sizes in order to meet the needs of specific applications. IPMCs are well suited for low power electronics, sensors, micro-electronics, and MEMs and high temperature applications. This study investigates the role of mechanical engineering in IPMC capacitor design, manufacturing, and systems integration.

3D Printing of Nanostructures Using Electrohydrodynamic Jet Printing for Surface Enhanced Raman Scattering (SERS) Based Optical Sensor: Savan Suri1; Konstantinos Sierros1; 1West Virginia University
    In this study, we introduce an inexpensive and a novel 3D printing process using the electrohydrodynamic jet printing methodology. A wide variety of controlled silver nano islands and nano lines have been printed to measure plasmonic response to fabricate cheaper and faster Surface-Enhanced Raman Scattering (SERS) sensors. The jetting parameters have been developed to control the size, shape and periodicity of the nano metallic patterns. These structural differences are compared with the changes in SERS measurements comprising of both localized and propagating surface plasmons. The above printing process can be used to create a highly ordered, 3 dimensional, multilayered, plasmonic platforms to enhance the electromagnetic hotspots for high SERS enhancement factor (EF). Such a platform can also be used to detect multiple species in chemical, biological and optical sensors on the same platform.

Computational Modeling of Transport Properties of Functional Conductive Inks Using Molecular Dynamic Simulation for Printed Electronics: Patrick Dzisah1; Nuggehalli Ravindra1; 1New Jersey Institute of Technology
    The emerging applications in electronics have increased the need for optimizing the use of conductive inks in specialized printing processes. Increased demand, continuous material costs, unpredictable transport properties, difficulty of fabricating high-accuracy conductive lines, poor performance of printed films, device miniaturization and integration, are currently some of the challenges faced by flexible printed electronics. A qualitative determination of surface and transport properties such as diffusivity, viscosity, electrical and thermal conductivity, of nanoparticle conductive inks is essential for understanding device performance and optimization of printed devices. In this study, the relationship between nanoparticle conductive ink content and transport properties are investigated in non-Newtonian fluids using modified molecular dynamic simulations. The fluid dependence on extrinsic parameters such as pressure, temperature, composition, and atomistic processes underlying them are explored. The phenomenological and physical links between electrical conductivity, diffusivity, viscosity and ink concentration due to structural rearrangement in the printed nanoparticle films are discussed.
