UNIVERSITITY COLLEGE CORK (UCC) Faculty of Chemical AMBER and CRANN researchers and interdisciplinary teams and Trinity College Dublin (TCD) The Faculty of Physics warns the exposure to harmful gases to individuals for a sensor for detoured monitors. We have developed technology. 。

These results are published in the ACS Applied Nano Materials.

Low air quality has a significant impact on health, ecosystems, and overall quality of life. Therefore, it is essential to maintain good air quality for human happiness, environment, and economic prosperity. One of the dangerous gas that seriously threatens health is nitrogen dioxide (No2). No2 is released into the atmosphere through fuel burning, industrial emissions, gas cooking, and other sources.

NO2 has a serious risk of human health, leading to short -term symptoms such as dyspnea and long -term respiratory problems related to long -term exposure. Regulatory organizations such as the Environmental Protection Agency (EPA) and the European Committee have established the NO2 exposure restrictions to address these health concerns.

For the past 20 years, a significant advancement of gas sensor technology has been made, but the challenge is real -time monitoring, room temperature movement, sensitivity, and selectivity.

Most NO2 sensors are unrealistic to integrate into wearable technology. The current method for measuring No2 requires expensive measurements, emphasizing the need to develop low -cost sensor technology for more wider surveillance of this important pollutant. I am.

“Amber is actively developing a 2D material network on the flexible polyethylene telephate (PET) basis,” said Cork, a deputy director of the College University of Chemical University. , Transparency to strengthen wearable technology for real -time temperament and advanced sensing.

In 2023, recent large -scale flashes at the European level in the West Coast and Croatia, Portugal, Greece, Spain, Italy, and Algeria are burned out not only for leaves, but also in housing, commercial and industrial units and vehicles. I did it. Dangerous gas emissions are difficult to determine first.

This emphasizes the growing need for low -cost scalable technologies, such as personal aviation monitors, because our atmosphere does not know the boundaries or boundaries.
