Scientists have created a new wearable UV detection system that can do just that Help prevent sunburn,
Nearly nine in ten skin cancer cases in the UK caused by coming in contact with Too much ultraviolet (UV) radiation Sun and sunbeds, according to cancer Research,
ultraviolet radiation There can be considerable harm to skin health. Three types – UVAUVB, and UVC – UVA is the most dangerous, as its longer wavelength enables it to cross the ozone layer and penetrate deep into human skin.
wearing sunscreen provides useful protection against UVA, but this new fully transparent device combines a smart fone And tracks the user’s exposure to it, which can help prevent the risk of skin damage.
Unlike existing opaque sensors, this new, clear device “enables seamless integration with the environment and users, especially in wearable devices such as smart watches, glasses and patches, where transparent UV detection is required”, according to study author Yoo Bin Kim at Songsil University in Seoul, South Korea.
The researchers concluded, “This health care device integrated with smartphones demonstrates its potential as a practical approach to preventing the risks associated with long-term UV exposure.”
Study, published in journal science advancementThe transmittance of the sensor tested – the amount of light that successfully passes through the opaque device and reaches its internal semiconductor. The researchers found that the sensor achieved an average transmission of 75 percent.
This sensor was then connected to a smartphone, and in real time, the system collected data about sunlight and warned the user when they received 80 percent of their limit before the predicted occurrence of sunburn.
Long-term exposure to UVA causes skin aging and increases the risk of cancer, and the study authors argued that real-time monitoring is necessary to prevent skin damage and related health risks.
However, that doesn’t mean you should stop taking other precautions, like wearing sunscreen and seeking shade in the afternoon sun, experts say. This device is designed as an additional tool to prevent sun damage.
Cancer research has warned that sunbathing just once every two years could triple the risk of skin cancer compared to never sunbathing.
Research shows that just one severe sunburn during childhood or adolescence nearly doubles a person’s risk of developing melanoma later in life – the deadliest type of skin cancer.
The NHS recommends people wear a sun protection factor (SPF) of at least 30 to protect against UVB rays and at least 4-star UVA protection to prevent sun damage.
