Wearable and ultra-thin electronic sensors for non-invasive real-time monitoring of operators in hazardous conditions

Introduction. Continuous, non-invasive monitoring of workers' physiological parameters in high-risk work environments is a priority challenge for occupational medicine, aimed at preventing stress, fatigue, and potentially dangerous acute events. This contribution describes the development and validation of a new generation of wearable, flexible, and ultra-thin electronic sensors designed to be worn non-invasively. Objectives. The main functionalities that will be presented and discussed concern the real-time detection of vital parameters such as body temperature, heart rate, skin conductance, and hydration level, as well as the quantitative monitoring of exposure to ionizing radiation. Methods. Thanks to the use of biocompatible materials and advanced microelectronic technologies, these devices ensure high accuracy and comfort, minimizing interference with the operator's movements and work activities. The collected data can be transmitted wirelessly to a centralized monitoring platform, allowing for continuous analysis of the parameters and the activation of any predictive alarms. Results and Conclusions. Initial experimental studies conducted in simulated and real environments (industrial and emergency services sectors) have highlighted the sensors' ability to identify situations of physical overload or danger early on, offering a potentially decisive tool for personalized prevention and risk management in the workplace.
