Doctoral Researcher Kim Jong-wook Develops a Wearable Wireless Electron Patch with KAIST Research Team
A Wearable Wireless Electron Patch (yna.co.kr)

On May 6th, Kim Jong-wook, a doctoral researcher in the Department of Chemical Engineering, developed a wireless electron patch with the research team from the Korea Advanced Institute of Science and Technology (KAIST). This patch allows for the calculation of the quantitative amount and rate of sweat by using sweat. Previously, the patch used blood to measure this. However, unlike blood, sweat can be more easily collected through non-invasive measurement. For this reason, live measurement of sweat flux and total loss is a fundamental requirement for more accurate measurement. Therefore, the research team incorporated a microfluidic system that allows the analysis of components of sweat into the wireless electron patch. It successfully measures the concentration of chloride, glucose, creatine, and hydrogen ion exponents in sweat and body flux at the same time. As it is a wireless patch, this data can be checked through smartphone applications using Bluetooth communication. The research is meaningful in that it separated the channel of sweat and electronic circuits, thereby becoming corrosion resistant. Moreover, the joint team expected the patch to be applied to diverse fields as it is attached with an internal sensor that can instantly detect changes in skin temperature by sweat emission. This research was published in the international journal Nature Electronics on March 29th.
