## Description

- description: "Humidity sensitivity is evaluated for chemically synthesized ZnAl2O4/Al
    devices. We succeeded\r\nin synthesizing the ZnAl2O4/Al device by applying chemical
    techniques only. Hydrothermal\r\ntreatment for the anodized aluminum (AlOx/Al)
    gives us the device of the ZnAl2O4/Al structure.\r\nAll fabrication processes
    were conducted under 400 \x0EC. The key was focusing on ZnAl2O4 as the\r\nsensing
    material instead of MgAl2O4, which is generally investigated as the humidity sensor.
    The\r\nevaluation of this ZnAl2O4/Al device clarified its effectiveness as a sensor.
    Both electrical capacitance,\r\nCp, and the resistivity, Rp, measured by an LCR
    meter, obviously responded to the humidity with\r\ngood sensitivity and appreciable
    repeatability. Our synthesis technique is possible in principle to\r\nimprove
    on the process for the device with a complex structure providing a large surface
    area. These\r\ncharacteristics are believed to expand the application study of
    spinel aluminate devices as the sensor."
