Stretchable, Skin-Breathable, and Ultrasensitive Respiration Sensor Using Graphite on Paper With Smart Structures
Tập 22 Số 17 - Trang 16804-16810 - 2022
Healthy sleep is an important indicator of good physical and mental health. The current technology employed for monitoring sleep quality is typically expensive and invasive, which demands innovations in respiration monitoring. In addition, recent effort in developing wearable respiration sensors has faced great challenges in concurrently obtaining low cost, high stretchability, and high sensitivit......

Pattern analysis for machine olfaction: a review
Tập 2 Số 3 - Trang 189-202 - 2002
Pattern analysis constitutes a critical building block in the development of gas sensor array instruments capable of detecting, identifying, and measuring volatile compounds, a technology that has been proposed as an artificial substitute for the human olfactory system. The successful design of a pattern analysis system for machine olfaction requires a careful consideration of the various issues i......

Distributed odor source localization
Tập 2 Số 3 - Trang 260-271 - 2002
This paper presents an investigation of odor localization by groups of autonomous mobile robots. First, we describe a distributed algorithm by which groups of agents can solve the full odor localization task. Next, we establish that conducting polymer-based odor sensors possess the combination of speed and sensitivity necessary to enable real world odor plume tracing and we demonstrate that simple......

Air quality monitoring and fire detection with the Karlsruhe electronic micronose KAMINA
Tập 2 Số 3 - Trang 179-188 - 2002
An indoor air monitoring device is one of the most prominent consumer applications of an electronic nose (EN). Integral gas analysis similar to biogenic odor perception can be a versatile tool to obtain continuous information about pollutants, odors, and air compositions indicating gaseous precursors of dangers such as fires. However, an EN to be used as a common household device has to combine hi......

Learning from data: a tutorial with emphasis on modern pattern recognition methods
Tập 2 Số 3 - Trang 203-217 - 2002
The purposes of this tutorial are twofold. First, it reviews the classical statistical learning scenario by highlighting its fundamental taxonomies and its key aspects. The second aim of the paper is to introduce some modern (ensembles) methods developed inside the machine learning field. The tutorial starts by putting the topic of supervised learning into the broader context of data analysis and ......

SnO/sub 2/ gas sensing array for combustible and explosive gas leakage recognition
Tập 2 Số 3 - Trang 140-149 - 2002
A gas-sensing array with ten different SnO/sub 2/ sensors was fabricated on a substrate for the purpose of recognizing various kinds and quantities of indoor combustible gas leakages, such as methane, propane, butane, LPG, and carbon monoxide, within their respective threshold limit value (TLV) and lower explosion limit (LEL) range. Nano-sized sensing materials with high surface areas were prepare......

Medical diagnosis with the gradient microarray of the KAMINA
Tập 2 Số 3 - Trang 254-259 - 2002
Investigations with human breath and cultures of oral bacteria have been performed to examine the analytical performance of the KAMINA gradient microarray based on a segmented metal oxide layer. Standard microarray chips with 38 segments, one chip equipped with platinum doped SnO/sub 2/ and the other with WO/sub 3/, were inspected. The results show that the gradient microarray is able to detect ac......

Optimization of gas-sensitive polymer arrays using combinations of heterogeneous and homogeneous subarrays
Tập 2 Số 3 - Trang 169-178 - 2002
Results for optimizing an array of conducting polymer gas sensors for sensing one of five analytes in the presence of up to four interferents are presented. The optimized array consists of subarrays of homogeneous (like) sensors contributing to a larger heterogeneous array of up to ten points (unlike sensors) in multidimensional sensor space. The optimization techniques presented here are linear, ......

Effects of electrode configuration on polymer carbon-black composite chemical vapor sensor performance
Tập 2 Số 3 - Trang 160-168 - 2002
The performance of polymer carbon-black composite chemical vapor sensors as a function of underlying electrode size and geometry has been studied. The sensor performance parameters investigated were sensor response magnitude to a toluene analyte (100, 500, and 1000 ppm), fundamental sensor noise in the presence of air, and two concentrations of toluene (100 and 500 ppm), and signal-to-noise ratio ......

Bioelectronic sniffer device for trimethylamine vapor using flavin containing monooxygenase
Tập 2 Số 3 - Trang 133-139 - 2002
A bioelectronic sniffer device for trimethylamine (TMA) in the gas phase "fish-odor substance" was constructed using a flavin-containing monooxygenase 3 (FMO3, one of xeno-biotic metabolizing enzymes) and a reaction unit with both gas and liquid cells separated by a porous poly(tetrafluoroethylene) diaphragm membrane (pore size: 30-60 /spl mu/m, thickness: 0.20 mm). A substrate regeneration cycle ......
