There is increasing interest in the utilisation of medical gases, such as ozone, for the treatment of herniated disks, peripheral artery diseases, and chronic wounds, and for dentistry. Currently, the in situ measurement of the dissolved ozone concentration during the medical procedures in human bodily liquids and tissues is not possible. Further research is necessary to enable the integration of ozone sensors in medical and bioanalytical devices. In the present review, we report selected recent developments in ozone sensor technology (2016–2020). The sensors are subdivided into ozone gas sensors and dissolved ozone sensors. The focus thereby lies upon amperometric and impedimetric as well as optical measurement methods. The progress made in various areas—such as measurement temperature, measurement range, response time, and recovery time—is presented. As inkjet-printing is a new promising technology for embedding sensors in medical and bioanalytical devices, the present review includes a brief overview of the current approaches of inkjet-printed ozone sensors.

医疗应用臭氧传感器技术的最新发展。

人们对利用医用气体（例如臭氧）来治疗椎间盘突出症，周围动脉疾病和慢性伤口以及牙科的兴趣日益浓厚。当前，在医学过程中人体液体和组织中原位测量溶解的臭氧浓度是不可能的。为了使臭氧传感器集成到医疗和生物分析设备中，还需要进行进一步的研究。在本综述中，我们报告了臭氧传感器技术的最新进展（2016–2020年）。传感器分为臭氧气体传感器和溶解臭氧传感器。因此，重点在于安培和阻抗以及光学测量方法。测量温度，测量范围，响应时间，以及恢复时间。由于喷墨打印是将传感器嵌入医疗和生物分析设备中的一种新的有前途的技术，因此本综述包括对喷墨打印臭氧传感器的当前方法的简要概述。
