Glass is well established as wafer or panel substrate for applications like capping of image sensors or as low loss carrier for integrated passive devices. Glass substrates with higher functionality becomes more attractive for the advanced packaging due the improvement of glass processing and the increased implementation of photonic packaging which is demanded for higher data transfer rates. The through...
In this paper, we have presented the design and invention of an electronic nose (E-nose) that can work and analyze the results via a network system such as LAN or WiFi. The MWCNTs/polymer composites were used as a gas sensor array. The constant current circuit was newly designed for gas sensor measurement. The fabricated E-nose showed a high performance for indoor air monitoring with very low noise.
Several indoor chemical contaminants such as CO and NO2 are highly toxic. Inhalation of CO or NO2 as low as ppm level may cause respiratory distress or failure. Therefore, detection of indoor air is very important in the industrial, medical, and environmental applications. In this paper, a new electronic nose (E-nose) architecture has been proposed for the real-time quantification and qualification...
Homeland security basically needs devices that can detect, track, and identify a terrorist from a distance. Body odor recognition offers an opportunity to confirm a person's identity based on one's unique odor pattern. In this paper, we have reported how to invent a networked electronic nose (E-nose), which can detect and recognize human odors from the armpit region. An array of metal oxide sensors...
Optical electronic nose (olfactory sensing) technologies have recently become a convenient technique to identify the quality of food and beverage products based on the odor classification. In this paper, we reported an optical-based electronic nose system consisting of thin-film sensing materials, array of light emitting diode (LED), photo-detector and pattern recognition program. The organic mixtures...
Focus of this work was the development and optimization of process techniques for the application of Polyimide (PI) or Polybenzoxazole (PBO) to act as dielectric material together with semi-additive copper as conductive material in a thin film multilayer buildup, which is suitable for the integration of all three types of passive components. A thin film set up including seven layers was used to create...
