This paper discussed the development of atomic oxygen flux measurement on the surface of spacecraft and presented an idea of a novel atomic oxygen flux sensor. This sensor used YSZ(yttria-stabilized zirconia)as sensitive material. The method calculated the atomic oxygen flux by testing the impedance of YSZ. At the same time,osmium was used to calibrate the sensor. This design can solve the problems of measuring the atomic oxygen flux in a long period of time and in-situ calibration.
