  • Patent number: 9759688
    Abstract: A gas sensor utilizing carbon nanotubes (CNTs) is disclosed. The sensor can include a patch antenna, a feed line, and a stub line. The stub line can include a carbon nanotube (CNT) thin-film layer for gas detection. The CNTs can be functionalized to detect one or more analytes with specificity designed to detect, for example, environmental air contaminants, hazardous gases, or explosives. The sensor can provide extremely sensitive gas detection by monitoring the shift in resonant frequency of the sensor circuit resulting from the adsorption of the analyte by the CNT thin-film layer. The sensor can be manufactured using inkjet printing technologies to reduce costs. The integration of an efficient antenna on the same substrate as the sensor enables wireless applications of the sensor without additional components, for wireless standoff chemical sensing applications including, for example, defense, industrial monitoring, environmental sensing, automobile exhaust analysis, and healthcare applications.

  • Patent number: 9689865
    Abstract: The present invention provides a personal hygiene item. In simple terms, one of the main features of the present invention is to provide a low-cost personal hygiene item capable of providing a multi-component detection function. The personal hygiene item of the present invention mainly comprises a first material layer and a second material layer. The first material layer is made of hydrophobic material, and the second material layer is disposed thereon. Also, the second material layer comprises a discolored portion. In actual practice, a fluid under test contacts with the corresponding discolored portions via the hydrophobic layer of second material layer for a color changing reaction. Meanwhile, since the hydrophilic performance of the discolored portion is better than the hydrophilic performance of the hydrophilic layer, the back permeation of the fluid under test can herein be prevented.
