UV sensors are used to detect and measure levels of ultraviolet radiation in the environment, especially levels that can be harmful to humans, such as those that cause skin damage, premature aging, or even skin cancer. Accurately monitoring UV intensity plays an important role in protecting human health, helping people take appropriate precautions when exposed to sunlight.
However, the applications of UV sensors are not limited to healthcare or personal protection. They are also widely used in many other fields such as the military, where detecting specific signals or environmental conditions is essential; in optical communication to support signal transmission; and in environmental monitoring to track factors that affect ecosystems.
Although graphene itself may not exhibit very high photoresponsivity, when combined with other materials it can be used to create UV sensors with many outstanding advantages. These sensors are not only flexible and transparent but also environmentally friendly and low-cost to produce. Such properties open up great potential for applications in advanced technologies, especially wearable electronic devices.
In the near future, the development of graphene-based UV sensors is expected to contribute to the creation of smarter, more convenient, and safer technological products, while also enhancing the protection of human health and the environment.
