Development of an Electronic Prototype for Stress Measurement Using Physiological Variables in School Teachers

Stress was identified as an innate response of the body to challenging and demanding situations, and it emerged as a growing concern in the workplace. The International Labour Organization (ILO) defined it as a global epidemic affecting workers of various ages and professions. Given this reality, the research presented here delved into the study of physiological signals, which were considered crucial indicators to determine the presence of stress. Using the Device for Detecting the Presence of Stress (DDPS), various physiological responses were recorded, including electrodermal activity (EDA), skin temperature (ST), and electrocardiography (ECG). Tests carried out in controlled environments confirmed that the DDPS's accuracy was on average 68 % in identifying episodes of stress in teachers.
