Bottom-up Growth Design and Property Control for Dielectric Thin Films and Nanostructures: Tomoaki Yamada1; 1Nagoya University
    Dielectric, piezoelectric and ferroelectric thin films and nanostructures have been intensively studied for emerging functional devices. In such low-dimensional nano-scale systems, the properties are often remarkably influenced by the mechanical and electrostatic boundary conditions. In this presentation, we introduce our bottom-up growth approaches to manipulating them. For instance, 2-step growth method using a low-temperature buffer layer was employed to modify strain in (Ba,Sr)TiO3 films, which enabled to control the dielectric tunability using a substrate of the same kind. Self-assembled growth of BaTiO3-CeO2 oriented composite films resulted in the significantly enhanced dielectric nonlinearity. Self-assembled growth of epitaxial Pb(Zr,Ti)O3 nanorods resulted in the pure c-domain structure due to their asymmetric electrostatic boundary condition. Because the nanorods are almost mechanically free from the substrate, they achieved the piezoelectric response as large as that for a single-domain crystal.

Novel Design and Fabrication of Piezoelectric MEMS and their Application to IoT: Takeshi Kobayashi1; 1National Institute of Advanced Industrial Science and Technology (AIST)
    Piezoelectric MEMS is widely applied to inkjet heads, gyro, hard disk slider heads, etc. Key features of the piezoelectric MEMS integration of sensor and/or actuator element onto the thin MEMS structure. Based on the features, I have developed a uniquely designed self-sensitive resonant cantilevers, optical scanners, and self-amplification accelerometer. I have also developed ultra-thin piezoelectric MEMS technology, where only thin structure of piezoelectric MEMS is transferred onto flexible printed circuit substrate. Using the technology, I have developed a dynamic strain sensor array sheet for monitoring cracks in highway bridges. Recently, I have developing the ultra-thin piezoelectric MEMS for the application to speakers and haptics devices.

Bulk Nanostructured Ceramics Using Novel Processing Techniques: Edward Gorzkowski1; 1Naval Research Laboratory
    At the US Naval Research Lab we have been utilizing and developing processing routes in order to tailor unique microstructures in metals and ceramics. These techniques include 2 stage sintering, aerosol deposition, high pressure processing, microwave sintering, and electrically assisted sintering. The goal is to create fully dense bulk nanostructured ceramics. The impetus for this is the many theoretical and experimental studies showing tremendous enhancements in structural and functional properties of nanostructured materials such as improvements in magnetic exchange coupling, thermoelectric energy conversion, and mechanical response. However, these improvements are generally only expected when porosity is negligible and the microstructural length scales are well below 50 nm, which is a technological challenge, especially in nanocrystalline ceramics processing. Two techniques that will be highlighted are NRL’s Environmentally Controlled Pressure Assisted Sintering (EC-PAS) and Aerosol Deposition. Using these approaches, fully-dense nanocrystalline ceramics and thick films with grain sizes <10nm have been synthesized..

Development of Co-fired All Solid State Lithium Ion Battery with Multilayer Ceramic Technology: Hiroshi Sato1; 1TDK Electronics GmbH & Co OG
     Co-fired all-solid-state lithium-ion battery with multilayer ceramic technology attracted attention as safe power sources in the field of small devices such as IoT, wearable devices, and medical applications. Multilayer ceramics technology enables to make thin solid electrolyte layer down to sub-micron order, which can cover low ionic conductivity of solid electrolyte by its thickness control. Also, since it is easy to make parallel connection of battery inner structure, capacity and inner resistance can be controlled by the number of layers. In addition, this technology leads to high volume manufacturing by using similar manufacturing equipment for multilayer electronic components such as multilayer ceramic capacitor. This presentation will describe key points of material selection and process electrode structure optimization to make co-fired all solid battery with multilayer ceramic technology.

Energy Harvesting Materials and Devices: Shashank Priya1; 1Pennsylvania State University
    The synergy between the smart materials – power source – self-powered systems has provided the paradigm of “self-sustainable component and systems” that is driving the emergence of efficient and high-performance architectures. There is significant reduction in size and weight of the self-sustainable architectures as compared to traditional “grid-powered” or battery-powered devices. Examples illustrating these self-sustainable architectures will be provided covering solar, thermal, magnetic field and vibration energy harvesting. The presentation will emphasize advances made in synthesis of textured piezoelectrics, organo-halide perovskites, thermoelectrics and magnetoelectric composites. Synthesis techniques such as spark plasma sintering, dry/wet aerosol deposition, laser annealing, and template grain growth will be discussed. These synthesis methods have provided the opportunity to develop materials with specific figure of merit. Interface design through laser annealing has opened the opportunity to achieve high coupling factors responsible for high power density. In-depth discussion will be provided on the design, modeling and testing procedures.
