Scientists have created a very small, flexible, battery-free sensor that can track the amount of sunlight a person experiences in a sunny atmosphere.
The device, which is no more than the size of a coin and can be worn, has wireless capabilities that allow users to see data on the amount of ultraviolet radiation through the smartphone.
Exposure to ultraviolet radiation increases the risk of skin cancer. However, the sensitive device can also be used to determine the amount of sunlight required to be exposed under certain conditions.
For example, it is common for preterm infants to be born with bile and to be treated with blue light. With these innovative devices, nurses and doctors can ensure that the baby has an appropriate dose.
Although this sensor is not the first to measure ultraviolet light, it is the first to do this without a battery. It not only comes in different sizes, but also can withstand the wash cycle in the electric washing machine.
The study was finally published in the journal Science Transnational Medicine.
