摘　　要：氧气是人类和其他大部分生命体赖以生存的物质基础,环境中过低和过高的氧气浓度都会影响人的身体健康,甚至危及生命安全。因此,针对未知环境空气中氧气浓度的监测对于保障作业人员的生命安全尤为必要。近年来,随着智能穿戴产业的迅速发展,柔性氧气传感器由于结构适应性强、可共形设计以及轻量等特点越来越受到学术界与产业界的关注。本工作采用1-丁基-3-甲基咪唑六氟磷酸盐[BMIM]PF6离子液体作为电解质,聚对苯二甲酸乙二醇酯(PET)为柔性衬底,通过蒸镀金电极并采用柔性封装工艺,制备了一种柔性电化学氧气传感器,并系统研究了其应用性能。所制备的氧气传感器在0%~60%的氧气浓度范围内表现出了良好的线性度(R2=0.974)、T90响应时间(约为20 s)、灵敏度(0.534)。该柔性电化学氧气传感器在智能穿戴、工业安防等领域显示出广阔的应用前景。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 re-cent 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 O_(2)electrochemical sensor based on 1-butyl-3-methylimidazolium hexafluorophosphate[BMIM]PF6 ionic liquid electrolyte and polyethylene terephthalate(PET)flexible sub-strate by using electroplating and flexible encapsulation technology.The results show that the oxygen sensor has a good linearity(R^(2)=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.
