Rechargeable Lithium-ion Batteries For Wireless Smart Designs

Fusalba F., CEA-Liten, FR

Wireless communication is today considered as a disruptive technology. Indeed, even if wired systems can easily achieve 100% of reliability, it induces high amount of wiring, which has non negligible impact on the mass and [...]

Molecular Dynamics Simulation of Sensor-Enabled Geosynthetics

Hatami K., Yazdani H., Hawa T., Grady B.P., University of Oklahoma, US

Molecular Dynamics (MD) simulations are used to examine selected mechanical and electrical properties of Sensor-Enabled Geosynthetics (SEG) samples. Dreiding force field is adopted for the simulations which are carried out in the LAMMPS© environment. The [...]

Temperature and Strain Response of a Surface Acoustic Wave Sensor

Wilson W.C., Atkinson G.M., NASA Langley Research Center, US

A new multifunctional temperature and strain sensor is being investigated. The new sensor is based upon Surface Acoustic Wave (SAW) technology on a Langasite substrate. SAW sensors can be developed that respond to changes in [...]

CNTFETs fabricated using an Original Dynamic Air-Brush technique for SWCNTs deposition : application to gas sensing

Bondavalli P., Gorintin L., Feugnet G., Thales Research and Technology, FR

This contribution deals with Carbon Nanotubes Field Effect transistors (CNTFETs) based gas sensors fabricated using a completely new dynamic air-brush technique for SWCNTs deposition. More precisely, we have developed a machine which allows us the [...]

Low-cost Thin-film Transistor-based Microcantilever for Measuring Deflection

Lin P-Y, Cheng Y-J, Kuan S., Huang L-S., National Tainwan University, TW

Here, we firstly report the low-cost poly-Si TFT embedded in the high-stress region of the microcantilever (MCL) as a sensing transducer to convert local strain into an electrical signal.In this work, the verification of reproducible [...]

Agriculture Industry Sees Green in Wireless Technologies

Ersavas B., Comucicnao, Inc, US

While green is certainly considered good, applying advanced wireless technologies across the agriculture industry’s food chain is great. Bringing mature machine-to-machine (M2M) wireless communications to this broad industry – which includes growers, greenhouses, transporters and [...]
