Due to the rapid development and superb performance of electronic skin, we propose a highly sensitive and stretchable temperature and strain sensor. Silver nanoparticles coated carbon nanowires (Ag@CNT) nanomaterials with different Ag concentrations were synthesized. After the morphology and components of the nanomaterials were demonstrated, the sensors composed of Polydimethylsiloxane (PDMS) a...

Artificial neural networks (ANNs) are generally considered as the most promising pattern recognition method to process the signals from a hemical sensor array of electronic noses, which makes the system more bionics. This paper presents a chaotic neural network entitled KIII, which odeled olfactory systems, applied to an electronic nose to discriminate six typical volatile organic compounds (VO...

this research discusses the process of designing a conceptual model for a new information system, i.e. electronic document management system. the new system is designed for an educational institute (itvhe) whose managers are the research population. the research methodology is based on structured analysis and design methodology (ssadm). in the end, the new system proposed using a data flow diag...

An SOI CMOS multi-sensor MEMS chip, which can simultaneously measure temperature, pressure and flow rate, has been reported. The multi-sensor chip has been designed keeping in view the requirements of researchers interested in experimental fluid dynamics. The chip contains ten thermodiodes (temperature sensors), a piezoresistive-type pressure sensor and nine hot film-based flow rate sensors fab...

One of the main problems when working with electronic noses is the lack of reproducibility or repeatability of the sensor response, so that, if this problem is not properly considered, electronic noses can be useless, especially for quantitative analyses. On the other hand, irreproducibility is increased with portable and low cost electronic noses where laboratory equipment like gas zero genera...

Compared with the use of other types sensors, there are significant advantages in making measurements low speed gas flows by using a fiber-optic ‘hot-wire’ sensor. Measurements this type intrinsically safe fiber optic technology play an important role industry, especially coal mine clearance, roadway ventilation and fire safety warning. However, ‘line-diameter ratio’ wind sensor described previ...

An instrument for electronic odour sensing has been developed and used to classify many different materials, including beers, spirits and alcohols. The next stage in development is to begin to relate subjective odour descriptors (e.g. fruity, minty) to quantitative sensor array measurements. Both neural network and multivariate statistical techniques are required to accomplish this task . The u...
