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...

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 ...

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 ...

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...

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...

Identification of odors using a sensor array with kinetic working temperature and Fourier spectrum analysis
Tập 2 Số 3 - Trang 230-234 - 2002
A method for the identification of odors using a dynamically driven sensor array
has been developed, in which transient responses of the sensor array were used
to recognize target odors. Fourier transformation was used to transform the
transient response curves of the sensor array into Fourier spectra, and patterns
composed of some of the magnitudes in the spectra were used in the pattern
recognit...

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...

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...

Gas sensitivity comparison of polymer coated SAW and STW resonators operating at the same acoustic wave length
Tập 2 Số 3 - Trang 150-159 - 2002
Results from systematic gas sensing experiments on polymer coated
surface-transverse-wave (STW) and surface-acoustic-wave (SAW) based two-port
resonators on rotated Y-cut quartz, operating at the same acoustic wavelength of
7.22 /spl mu/m, are presented. The acoustic devices are coated with
chemosensitive films of different viscoelastic properties and thicknesses, such
as solid hexamethyldisiloxan...
