Detection of Skin RGB Color with a Battery-Free NFC Skincare Device

Sun tanning is a process in which color of the skin changes, while staying in the sun for a prolong time, caused by the ultraviolet (UV) radiations. In this study, we developed a novel, smart, skincare RGB color device that can detect the change in RGB color of the skin. The device could also harvest its energy from the near field communication (NFC) enabled smartphone, thus providing battery-less approach for the skincare support. Our smart skincare RGB device is integrated with two sensors: One for the detection of skin RGB color, and another for the detection of UV radiations from the sun. Based on the in vivo experimental results on different subjects, it was noted that different subjects were having different skin color types, therefore; change in RGB was different for each subject. Android application interface has also been provided in order to make the usage of this skincare device at ease. Finally, our smart skincare device is enclosed in a flexible 3D object that provides a very easy and convenient way to use, while taking it in the outside environment.
