Conductive textiles that change their electrical properties as a result of the environmental impact can be used as sensors. Smart textiles possess the properties of conventional textile materials and carry additive functional values. Typical examples are textiles that react to deformations such as pressure sensors, stretch sensors, and breathing sensors. Different physical principles are adopted to reach the same purpose, such as capacitive or resistive behavior of the textile sensor. On the other hand, biochemical, optical, temperature, humidity, and biopotential sensors can be made with smart textiles. [Pg.82]

Small, portable sensors are now available to monitor the air we breathe for such toxins as carbon monoxide, CO. As soon as the air contains more than a critical concentration of CO, the sensor alerts the householder, who then opens a window or identifies the source of the gas. [Pg.224]

Figure 11. Comparison of a wearable foam sensor integrated into a shirt, and a reference airflow monitor (facemask) for monitoring breathing during treadmill experiments. The results (bottom) indicate that these types of innocuous wearable sensors can provide important information on general heath indicators such as breathing [27]. Figure 11.

Due to a combination of the modified technique for sensor analysis of composite gas mixture with unique properties of the gas-sensitive point-contact matrix, a complex dynamic of interaction between sensitive matter and volatile compounds of exhaled air has been observed. This interaction is characterized by longer adsorption times. This behavior was not observed in our previous work on breath analysis where fihn samples were used [11]. [Pg.69]

It is known that chronic active inflammation in the gastric mucosa involves several interleukins (IL-8, IL-10 and IFN-gamma) known as immunological markers of the blood serum [33]. Hence it is possible that extensive gastric inflammation would lead to an increased release of some of the volatile inflammatory biomarkers in breath causing differences in the sensor response. [Pg.73]

This study demonstrates high efficacy and expediency of the TCNQ derivative-based point-contact multistracture as a prospective asset for development of new sensors. The complex character of the sensors response curve and correlation of some response characteristics with different pathological manifestations in human breath, may be further used as a noninvasive diagnostic method alternative to some invasive approaches currently routinely used in clinic. The need for reliable and feasible gas analysis methods functional in presence of atmospheric air, opens opportunities for application of the proposed sensor technique in other spheres of human activity. High sensitivity of the point-contact multistructure enabling analysis of composite gas mixtures, opens up wide possibilities to apply the demonstrated approach for environment and health protection, such as detection of trace amounts... [Pg.73]
