Novel gas sensors embroidered into fabric substrates based on polymers/ SWNT-COOH nanocomposites were proposed in this paper, aiming for their use as a wearable electronic nose (e-nose). The fabric-based chemical gas sensors were fabricated by two main processes: drop coating and embroidery. Four potential polymers (PVC, cumene-PSMA, PSE and(More)
To practice an efficient air quality management in livestocks, a standardized measurement technology has always been requested in order to assess the odor, of which results are acceptable by every party involved, i.e., the owner, the state and the public. This paper has reported on a prototype of portable electronic nose (e-nose) designed specially to(More)
A novel wearable electronic nose for armpit odor analysis is proposed by using a low-cost chemical sensor array integrated in a ZigBee wireless communication system. We report the development of a carbon nanotubes (CNTs)/polymer sensor array based on inkjet printing technology. With this technique both composite-like layer and actual composite film of(More)
The purpose of this work is a novel design and fabrication of wearable amine sensor embroidered into fabric substrates based on polymer/SWNT-COOH nanocomposite and applied as electronic nose (e-nose) system. The wearable amine sensors were fabricated by drop coating and embroidery processes. Various polymers, namely, polyvinyl chloride (PVC), cumene(More)
A portable electronic nose (e-nose) was appropriately designed for investigating quality of beverages such as juice or wine, etc. The e-nose system comprises of sample and reference containers, air flow unit, sensing unit and data acquisition unit. All of the hardware units were controlled by in-house software under LABVIEW program via USB port of a DAQ(More)
In this paper, we have developed a wearable electronic nose (e-nose) embedded on cloth for detecting the body odor of wearer, aiming to be a self-monitoring healthcare consumer electronics. This "smelling shirt" consists of eight on-fabric chemical gas sensors based on polymer/functionalized-SWCNTs simply fabricated by embroidering and drop coating process.(More)
Gas sensors based on carbon nanotube (CNT)/ polymer nanocomposite were fabricated by a fully inkjet-printing method. The CNT/polymer layers acting as sensing layer were prepared by 2 methods; (i) deposition of separated layer of CNT and polymer to form a composite-like structure at the interface and (ii) deposition of blend CNT and polymer to obtain(More)
A portable electronic nose (E-nose) based on metal oxide gas sensor was used for detection of a total volatile compound in soil headspace and greater wax moth (Galleria mellonella L.). Sensor elements were selected in order to possibly respond to a wide range of the volatiles including both of oxidizing and reducing gases. The aim of this work was to relate(More)
Thread-based gas sensor based on poly (styrenecomaleic acid) partial isobutyl/methyl mixed ester and multi-walled carbon nanotube (PSE/MWCNT) nanocomposite for NH<sub>3</sub> detection has been designed and created from two simple processes; crochet and immersion (dip) coating processes. This new dimension of fabric-based gas sensors fabrication is suitable(More)
