Gas Sensing Properties of Zn-Doped Anisometric Fe2O3 Nanoparticles

Kim T., Sharp A.C., Yim H., Guo B., Texas A&M University, College Station, US

In this study, we synthesized nanocrystalline Zn-doped Fe2O3 by flame spray pyrolysis under different conditions, and then investigated the gas sensing characteristics of these particles. The response of the gas sensor to acetone vapor in [...]

Pierced Sensor for Nano-Microscope

Sklyar R., Independent researcher, UA

For nonzero drain voltages the superconducting field-effect transistor (SuFET) absorbs low- frequency power of the average Josphson current and re-emits this power at extremely high frequencies. The feasibility of the transistor function on a yarn-like [...]

Fully On-Chip High Q Inductors Based on Microtechnologies

Shah K., Khalid N., Singh J., Le H.P., Devlin J., Sauli Z., La Trobe University, AU

The fast growing demand of wireless communications for voice and data has driven recent efforts to dramatically increase the levels of integration in radio frequency (RF) transceivers. Passive components such as inductor play important role [...]

Low Cost Paper Based Bowtie Tag Antenna for High Performance UHF RFID Applications

Amin Y., Prokkola S., Shao B., Hållstedt J., Chen Q., Tenhunen H., Zheng L-R, Royal Institute of Technology (KTH), SE

In this paper, we have realized a bowtie antenna for UHF RFID Tag with extended round corners for the first time printed on paper substrate. The state of the art CAD tool Ansoft® HFSS is [...]

Power consumption of microelectronic equipment for wireless sensor networks

Poole N., Mo T., Brusey J., Coventry University, UK

Study on Application of Piezoelectric Vibration Energy Harvesters for Powering of Wireless Sensor Nodes in Large Rotary Machine Diagnostic Systems

Pekoslawski B., Pietrzak P., Makowski M., Szafoni L., Napieralski A., Technical University of Lodz, PL

A condition monitoring of large rotary machines such as turbogenerators in power plants can be more convenient and less expensive when using a distributed measurement system with wireless sensor nodes. A battery-based powering of these [...]

Nanochip – Ultra-High Data Density MEMS Memory Device

Adams D., Belov N., Chou T-K., Heck J., Kim B., Knight G., Ma Q., Rao V., Tchelepi G., Nanochip, Inc., US

Nanochip developed a conceptual prototype of a probe storage device (nanochip). The device employs a ferroelectric non-volatile memory, which permits robust write, non-destructive read and simple data overwriting operations. Read-write operations require low power and [...]

Wireless sensor networks for activity monitoring in safety critical applications

Rednic R., Gaura E.I., Brusey J., Coventry University, UK

The ability to monitor posture is essential to many application areas, including virtual reality, health, and sports applications. The work here focuses on the use of postural monitoring monitoring in safety critical missions such as [...]

Priority Based Message Transmission over Unreliable Wireless Links for Safety Critical Monitoring Applications

Fei X., Kemp J., Gaura E.I., Brusey J., Cogent Computing Applied Research Centre, Coventry University, UK

In our prior work, a Body Sensor Network (BSN) system aimed at increasing safety of bomb disposal operatives during missions has been developed. Although this system served well the application at hand in terms of [...]

Wireless sensor networks for space applications

Benhaddou D., University of Houston, US

The application of Wireless Sensor Network (WSN) into time-sensitive applications, such as remote healthcare, fire tracking and industrial automation, demands support for emergency services with guaranteed Quality of Service (QoS) bounds. In particular, the continuous [...]
