“…The application of impedimetric and optical absorption sensors is mainly limited during medical therapy because of the high temperatures and UV light and may thereby be toxic for body liquids and tissues. Previous research [70,202] has already reported the optical absorption ozone measurement in the visible spectral light range, but the requirement of long optical path lengths limits the application. Moreover, Wu et al [203] also investigated the visible spectral light range.…”

“…The photodetector with sensing material is based on a glass or quartz substrate, which is covered by a sensing material. The sensing material can be made of ZnO [69], methylene blue [70], or poly(3,4-ethylenedioxythiophene) (PEDOT) doped with polystyrene-sulfonate (PSS) forming PEDOT:PSS [71,72]. Table 2 shows an overview of currently utilized materials for the main components of amperometric, impedimetric, and optical sensors, as well as substrates and membranes.…”

The biocompatibility of medical sensors is of great importance. In order to prevent harm of the patient during measurement, this aspect must be considered throughout the entire design process. Biocompatibility can be achieved by various methods. For example, the sensor can be encapsulated, only biocompatible materials can be used for the sensor, or anti-inflammatory agents can be applied to the surface of the sensor. In this paper the focus is on sensors fully fabricated from biocompatible materials. Two exemplary inkjet-printed amperometric and impedimetric sensors are systematically assessed regarding their biocompatibility. Both sensors can be used for the measurement of dissolved ozone during oxygen-ozone injection therapy. For the sensors each material is evaluated with respect to the international standard ISO 10993. Overall, many amperometric and impedimetric sensors are fabricated from a small set of materials. The assessment reveals that for this specific application an amperometric sensor consisting of gold and silver nanoparticle inks, inkjet-printed on a polydimethylsiloxane membrane, and passivated with SU-8 ink offers the highest biocompatibility and reaches a good compliance with other important requirements. In addition, biological characterization tests are required for the specific medical application to validate the biocompatibility. From this study, it can be concluded that the findings on biocompatibility can also be transferred to other sensors that are made of the same set of materials but are for other applications. This applies to oxygen, glucose, pH, hydrogen peroxide, sweat lactate, and acetone sensors.

Recent Developments in Ozone Sensor Technology for Medical Applications

et al. 2020

View full text Add to dashboard Cite

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.

In research work the problem of studying the process of ozone control with the help of electronic sensors is considered. In research work, special sensors were used, which are formed around coronary electrodes in the ozonator and to monitor the concentration of ozone in the room. This is because ozone is known to adversely affect human health if its maximum permissible air concentration exceeds 0.16 mg/m3. A small system of ozonators was developed in a special laboratory, theoretical and experimental tests were carried out. In practice, the obtained data and the electric diagram of the ozonator (on the ARDUINO platform) were collected. "Prana Air" sensors and current sensors were used to accurately determine the ozone (O3) concentration around the ozone nozzle to measure the current at the electrodes.
