将Na超导导体（Na superonic conductor， NASICON）与纳米（或纳米）层结合，制成了一种电流限制传感器。与使用NaNO的设备相比，使用NaNO的设备在200℃时具有更高的NO灵敏度。在0 ~ 80 ppm范围内，NaN0贴合器件的电流响应与NO浓度基本呈线性关系。此外，该装置对NO的选择性相对于通常共存于燃烧废气中的其他气体是相当高的。简要讨论了该装置的传感机理。
An amperometric limiting current NO, sensor was fabricated by combining a Na'conductor (Na superionic conductor, NASICON) with NaNO,(or NaNO,) layers. The device using NaNO, gave a much higher NO, sensitivity at 200 C compared to that using NaNO,. The current response of the NaN0,-attached device was almost linear with the NO, concentration in the range of 0 to 80 ppm. In addition, the selectivity of the device to NO, was fairly high with respect to other gases which are usually coexistent in combustion exhausts. A sensing mechanism of the device is discussed briefly.
