Smartphone Based Quantitative Stress Measurement System = Smartphone Based Quantitative Stress Measurement System

다국어 초록 (Multilingual Abstract)

Most people are currently under mental stress whereas its accurate diagnosis and measurement are very difficult to accomplish. For the precise measurement of the stress, either researchers or doctors conduct a survey, electroencephalogram, and bio-signal. The adverse symptoms, such as insomnia, lethargy, obesity, mental disorder, and cardiovascular disorder, will occur in the circumstances of excessive stress. In order to measure, manage, and transmit data simply and quickly via the only smartphone, the system for the quantitative analysis of cortisol by a smartphone linked with own lateral flow assay is built for the Point-of-care-testing (POCT) while the previous cortisol measurement and analysis are slow and complicated due to the small molecules of cortisol. Our system is composed of a smartphone, its holder, and stress sensor. First of all, in the case of the stress sensor, red color appears when conjugated with the antibody fixed on the strip through the sandwich assay reaction, and intensity of color appearance depends on the concentration of cortisol.
