In recent years, clinical studies have found that acetone concentration in exhaled breath can be taken as a characteristic marker of diabetes. Metal–oxide–semiconductor (MOS) materials are widely used in acetone gas sensors due to their low cost, high sensitivity, fast response/recovery time, and easy integration. This paper reviews recent progress in acetone sensors based on MOS materials for diabetes diagnosis. The methods of improving the performance of acetone sensor have been explored for comparison, especially in high humidity conditions. We summarize the current excellent methods of preparations of sensors based on MOSs and hope to provide some help for the progress of acetone sensors in the diagnosis of diabetes.

基于金属氧化物半导体材料的用于非侵入性诊断糖尿病的丙酮传感器

近年来，临床研究发现呼出气中的丙酮浓度可以作为糖尿病的特征性标志。金属氧化物半导体（MOS）材料因其低成本，高灵敏度，快速的响应/恢复时间以及易于集成而广泛用于丙酮气体传感器。本文回顾了基于MOS材料的用于糖尿病诊断的丙酮传感器的最新进展。为了比较，已经探索了改善丙酮传感器性能的方法，特别是在高湿度条件下。我们总结了目前基于MOS的传感器制备的优良方法，并希望为丙酮传感器在糖尿病诊断中的进展提供一些帮助。
