    • A compact oxygen sensor is provided, comprising a mixture of metal and metal oxide an enclosure containing said mixture, said enclosure capable of isolating said mixture from an environment external of said enclosure, and a first wire having a first end residing within the enclosure and having a second end exposed to the environment. Also provided is a method for the fabrication of an oxygen sensor, the method comprising confining a metal-metal oxide solid mixture to a container which consists of a single material permeable to oxygen ions, supplying an electrical conductor having a first end and a second end, whereby the first end resides inside the container as a reference (PO2)ref, and the second end resides outside the container in the atmosphere where oxygen partial pressure (PO2)ext is to be measured, and sealing the container with additional single material such that grain boundary sliding occurs between grains of the single material and grains of the additional single material.
    • 提供了一种紧凑的氧传感器,其包括金属和金属氧化物的混合物,所述外壳包含所述混合物,所述外壳能够将所述混合物与所述外壳外部的环境隔离;以及第一线,其具有驻留在所述外壳内的第一端,并且具有 暴露于环境的第二端。 还提供了一种用于制造氧传感器的方法,所述方法包括将金属 - 金属氧化物固体混合物限制在由可渗透氧离子的单一材料构成的容器中,供应具有第一端和第二端的电导体 ,由此第一端作为参考(PO 2 2)的参考位于容器内部,并且第二端位于容器内的氧分压(PO < SUB> 2 ext ,并用附加的单一材料密封容器,使得在单一材料的颗粒和附加单一材料的晶粒之间发生晶界滑动。
