This paper presents the development of a prototype device for predicting viral fever by monitoring stress levels through cortisol detection. Research indicates a negative correlation between the immune system’s strength and prolonged high stress levels. As stress increases, the immune system weakens, making individuals more susceptible to viral fevers and infections. The primary goal of this study is to design a device that tracks stress levels by measuring cortisol, a neuroendocrine hormone released during stress. Our approach utilizes a synthetic form of cortisol to construct the prototype, employing infrared (IR) sensing technology with IR LEDs and photodiodes to detect cortisol levels. This innovative device aims to provide an early warning system for viral infections by continuously monitoring and analyzing stress-induced hormonal changes.
