Shuai Xu and his colleagues at Northwestern University have developed a new technology capable of notifying the user when they are getting a sunburn. As someone with a forgetful mind and pale skin, I think this would be a very useful tool in helping me to remember to apply sunscreen.
Devices Past and Present
Devices like this have already been invented but were unsuccessful in several aspects. They were inappropriate for consumers as the devices were bulky, expensive, and not waterproof. Most people use sunscreen at a pool, beach, or sports games where waterproofing is necessary. At the beach and pool consumers would swim with the device and while in sports, sweat may hinder the device’s ability to function properly. The past designers also failed to consider that most consumers would be unable to carry a large device around with them in these locations and the average consumer would not be able to buy this device due to its cost.
Shuai Xu’s device, however, is more applicable. It is cost efficient, waterproof, and small. It has the ability to stick onto clothing, skin or jewelry, making it easy to use and conceal and is aesthetically appealing to customers. Below is an image of the device. As you can see it is very small and can be placed in unobtrusive places like a fingernail.
How it works
The device works by converting the UV light from the sun into electric current. The magnitude of that current is what is used to indicate the user’s exposure to the sun. There is also a feature that allows the user to view their level of sun exposure on their smartphone. A radio built into the device sends this information to the user. Each individual is evaluated individually as their level of exposure recorded is based on information provided by the user such as skin type, sunscreen applied, and clothing worn while exposed. Xu commented “This allows users to receive a very specific recommendation, “on this feature.
Conclusion
In conclusion, I appreciate this device because of its individual evaluations and function. I tend to burn easily. Even sitting inside, looking through a window for fifteen minutes or more could result in a sunburn. A device like this would remind me to go back inside or apply sunscreen. Adjusting the settings to suit myself would result in further decreasing the number of sunburns I receive. I also think this device could be beneficial in minimizing the number of cases of skin cancer. A surplus of UV exposure can result in skin cancer. A gentle reminder that sunscreen needs to be applied could make a difference in the amount of exposure a person gets, reducing the likelihood that they would develop skin cancer. Overall this device seems to be a good idea. I hope it is executed into the consumer market successfully.
