  • Patent number: 6705152
    Abstract: The present invention discloses a type of nanostructured ceramic platform for gas sensors and sensor arrays. These sensors comprise micromachined anodic aluminum oxide films, which contains extremely high density (e.g., 1011 cm−2) nanoscale pores. Sensing materials deposited inside this self-organized network of nanopores have ultra-high surface area and nanometer grain structure, therefore enabling high sensitivity. Refractory nature of alumina ceramic enables the desired robustness, long lifetime and stability in harsh environment. This sensor platform can been used for both chemical gas and physical (humidity, temperature) sensors and sensor arrays.

  • Patent number: 6610355
    Abstract: Ion conducting solid electrolytes are constructed from nanoscale precursor material. Nanocrystalline powders are pressed into disc structures and sintered to the appropriate degree of densification. Metallic material is mixed with 0 to 65 vol % nanostructured electrolyte powders to form a cermet mix and then coated on each side of the disc and fitted with electrical leads. The electrical conductivity of a Ag/YSZ/Ag cell so assembled exhibited about an order of magnitude enhancement in oxygen ion conductivity. As an oxygen-sensing element in a standard O2/Ag/YSZ/Ag/N2 set up, the nanocrystalline YSZ element exhibited commercially significant oxygen ion conductivity at low temperatures. The invention can be utilized to prepare nanostructured ion conducting solid electrolytes for a wide range of applications, including sensors, oxygen pumps, fuel cells, batteries, electrosynthesis reactors and catalytic membranes.
