Non Invasive Stress Detection in Pregnant Women: A Smart IOT based System

The effects of prenatal stress on the baby can occur through both direct and indirect pathways. Severe stress early in pregnancy has the most significant impact on birth outcomes such as preterm birth and low birth weight. Extensive research has been conducted on the continuous monitoring of vital signs, such as stress, using heart rate variability. Skin conductance response, a non-invasive physiological indicator of stress, has been increasingly applied in various fields. Compared to other stress measurement methods, skin conductance has demonstrated high correlation and accuracy. This article reviews recent studies on the use of skin conductance for stress detection in pregnant women, highlighting the methodologies and results. It also proposes a smart IoT-based system for monitoring stress in pregnant women.
