Innovative Gas Sensors for Sub-ppm Detection of Organophosphorus Nerve Agents by Chemically Functionalized Carbon Nanotube Field-Effect Transistors

Carella A., Caillier L., Clavaguera S., Celle C., Simonato J-P, CEA, FR

In this communication, we will present innovative sensors based on carbon nanotube field-effect transistors (CNT-FET) for detection of organophosphorus agents (OP, Sarin-like molecules). We have functionalized CNT with organic moieties reactive towards OPs that form [...]

Wireless SensorSystem with Bidirectional Communications

Husak M., Boura A., Jakovenko J., Czech Technical University in Prague, CZ

The system contains units: wireless, control, actuator, software equipment. RF wireless unit ensures wireless communication between control unit and sensors as well as wireless switch unit. The control unit controls system operation, i.e. communication transfer, [...]

Development of Quantitative Adhesive Force Measurement Systems for Flexible Electronics

Kim M., Park J., Choi B., Sogang University, KR

In this paper, a novel adhesive force measurement system is developed to measure adhesive forces from interacting surfaces. In previous paper, the adhesive force was measured with tens/hundreds of uN, and the displacement was measured [...]

Simple vertical velocity measurement system for different use

Husak M., Jakovenko J., Czech Technical University in Prague, Faculty of Electrical Engineering, CZ

The measurement of vertical velocity is necessary for different use. The solutions are based on principle of evaluating the change of an atmospheric pressure. The dependence which evaluates the vertical velocity is derived from the [...]

Modelling of Low Level Ionic Current Sensing Micro-tip

Memon S., Balachandran W., Brunel Univeristy, West London, UK

The authors of this paper are developing an appropriate micro/nano array sensors that is capable of sensing ionic currents in sweat fluid secreted from sweat pores on the finger ridges. In this paper we present [...]

Digital signal processing post-hybridization of DNA Biosensor

Afuwape S.A., National University, San Diego, US

The non-label DNA biosensor detects hybridization due to enhanced biomolecules surface-binding specifically on glass or plastic platform, now broadly extended to active surface such as field-effect transistors with scalability of the platform gate. The latter [...]

Mobility Effects on WCDMA Receivers in Indoor Areas

Alhloul S., Ahmad Alzahrani F., Albaha University, SA

This Paper presents important results in analysing the effects of mobility on WCDMA receivers. It takes a completly different apprach in translating the effects of mobility on WCDMA receivers. The mobility here is translated to [...]
