  • Publication number: 20180356388
    Abstract: Provided is a sensor which enables detection/identification of various types of fuels for automobiles by using simple devices. According to the present invention, high-octane gas, regular gas, diesel oil, heating oil, gasoline laced with heating oil, and the like can be clearly identified without using a large-scale analysis such as gas chromatography or mass spectroscopy by using a sensor having a structure in which a surface of a sensor body which detects a surface stress or the like is coated with particles modified with a hydrocarbon group such as an alkyl group.

  • Publication number: 20180017515
    Abstract: As a receptor layer, a film of a composite material of a base material such as a polymer and particles that adsorb an analyte is used. When the present invention is applied to a surface stress sensor or the like, the Young's modulus of the receptor layer, which significantly affects detection sensitivity, can be preset with a high degree of freedom, by independently selecting particles that adsorb a desired analyte and a base material that disperses said particles therein.

  • Publication number: 20180003604
    Abstract: According to improvement of the receptor layer of various sensors of the type for detecting physical parameters (for example, a surface stress sensor, QCM, and SPR), all of high sensitivity, selectivity, and durability are achieved simultaneously. A porous material or a particulate material, e.g., nanoparticles, is used in place of a uniform membrane which has been conventionally used as a receptor layer. Accordingly, the sensitivity can be controlled by changing the membrane thickness of the receptor layer, the selectivity can be controlled by changing a surface modifying group to be fixed on the porous material or particulate material, and the durability can be controlled by changing the composition and surface properties of the porous material or particulate material.
