The Smallest Non-Battery Device Can Alert People Of UV Overexposure

Scientists have come up with a super small, wearable device on the body that is able to alert the body to excessive exposure to ultraviolet rays (UV). UV is an important factor leading to skin cancer on humans. In particular, this device is not battery operated.

Currently, people do not know how much our bodies have received UV light. Thanks to this device, users can determine the amount of UV has impacted the body, especially protect those who have just experienced skin cancer.

The device is easy to wear on the human body, has a durable material and waterproof in order to give users more convenient while wearing it. It also has the ability to be linked to a smartphone, which is easily controlled by the user. This UV measurement is always on, but you do not need to charge it.

According to the published Science Translational Medicine, the device does not have any switches or batteries, and it does not wear out. The researchers claimed that the entire device was covered with thin transparent plastic.

The world's smallest wearable device that can warn people of overexposure to UV without using any battery

It is smaller than a chocolate grater and thinner than a credit card, the device can optimize the process of treating skin diseases, neonatal jaundice, seasonal effective disorders, and reducing the risk of burns. sun and skin cancer.

This device can record at the same time three separate wavelengths of light, giving the most accurate results. At an extremely compact and convenient size, users can attach it anywhere, such as sunglasses, hats, jackets or nails so it can measure the amount of UV they receive.

According to the data collected by the device, ultraviolet light was obtained in parlors of light in patients with atopic dermatitis and psoriasis. It is also equivalent to blue light therapy for neonatal jaundice in infants in intensive care.

In addition, it also has the ability to measure white exposure for seasonal depression. This is a mood disorder that happens at the same time or the same season every year.

Steve Xu, from Northwestern University in the US, said the precise need to accurately measure the level of ultraviolet light received by the body is becoming increasingly important to every human being living in this natural environment. Steve expects those who know about the danger of ultraviolet radiation to affect the human body should build better and healthier habits when going out in the sun.

In the United States, there are many people using this device in outdoor activities and giving it exposure to direct light in various forms.
