Additive Manufacturing and Characterization of Surface Acoustic Wave Devices: Nicholas McKibben1; Blake Ryel1; Alex Draper1; David Estrada1; Zhangxian Deng1; 1Boise State University
Piezoelectric materials output an electrical signal when mechanically stressed. Conversely, they change in shape when electrically activated. This effect, known as piezoelectricity, is instantaneous and highly linear, thus enabling innovations in surface acoustic wave (SAW) technology. A typical SAW transducer consists of one or more sets of interdigitated electrode pairs deposited onto the surface of a piezoelectric material. Driven by an electrical voltage, one interdigitated transducer (IDT) launches a surface acoustic wave, which is later transformed back to an electrical signal by the same or a different IDT. Substrate temperature and other environmental factors can be detected by tracking the time-of-flight, insertion loss, or frequency drift of the generated wave. SAW sensor fabrication traditionally relies on labor- and cost-intensive subtractive photolithographic processes that produce large amounts of hazardous corrosive wastes. This study uses an innovative aerosol jet printer to additively manufacture SAW sensors that are capable of detecting ambient environmental conditions.
A Comparative Study on Supercapacitors Formed with Different Graphene Based Hybrid Nanostructured Materials: Tasnim Mahjabin1; Md. Abdullah Al Amin1; 1Bangladesh University of Engineering and Technology
The development of high-performance energy-storage devices is crucial for satisfying the rapidly increasing demands for new applications that require high-power, high-energy, and cost-effective energy-storage systems (ESSs). The supercapacitors have high power densities, long lifetimes, short charging times, and excellent safety characteristics for fulfilling these requirements. If hybridization of different chemical substances is made, then even better properties can be achieved. In this review article different hybrid nanostructures for advanced supercapacitors are going to be discussed and compared to find the one which will demonstrate optimum properties. Here, graphene with its excellent electrical properties and porous carbon nanostructure resulting in large specific surface area will be kept as the constant part while various other chemical substances are going to be added to produce different supercapacitors. These will include: hybrid of (1) Graphene-Wrapped Li4Ti5O12 and Activated Carbon, (2) Copper oxide nanowire/graphene (3) Oxygen-deficient TiO2/graphene.
