Scientists have created a very small, flexible, battery-free device that tracks the amount of sunlight that a person feels in a sunny atmosphere.
The device, which does not exceed the size of a coin and can be worn, has wireless features that allow users to see data on the amount of ultraviolet radiation through the smartphone.
Exposure to ultraviolet rays increases the risk of skin cancer, but the sensitive device can also be used to determine the amount of sunlight required under certain conditions.
For example, premature babies are often born with bile and treated with blue light. With these innovative devices, nurses and doctors can make sure the baby gets the right dose.
Although this sensor is not the first to measure ultraviolet radiation, it is the first to operate without a battery. It comes not only in different sizes, but can also withstand the wash cycle in the electric washing machine.
The study was eventually published in the journal Transnational Science Medicine.
