摘要：
Oxygen is the basis for the survival of living organisms. Too low or too high oxygen concentration in the environment will affect people’ s health, and even endanger their lives. Therefore, it is necessary to detect the oxygen content, especially in a strange environment. In recent years, with the rapid development of intelligent wearable electronics, the development of flexible oxygen sensors has attracted more and more attention owning to their adaptability, conformal design and lightweight. In this work, we prepared a flexible O2 electrochemical sensor based on 1-butyl-3-methylimidazolium hexafluorophosphate [ BMIM] PF6 ionic liquid electrolyte and polyethylene terephthalate (PET) flexible substrate by using electroplating and flexible encapsulation technology. The results show that the oxygen sensor has a good linearity (R2 = 0. 974) when the oxygen concentration is in the range of 0% to 60%. The T90 response time of the sensor is about 20 s and the sensitivity is 0. 534. The flexible electrochemical oxygen sensor has a broad application prospect in intelligent wearables, industrial security, and other fields. © 2023 Cailiao Daobaoshe/ Materials Review.
