Toward a New Approach in Wearable Devices in Safety Monitoring: Miniaturization and 3D Space Utilization.

This commentary is focused on the requirements and general strategy of designing a multiparameter monitoring wrist-worn prototype. The solution is based on an innovative hardware approach to ensure the safety of working conditions through environmental parameter measurement. In some cases, exposure to environmental parameters for a long time can endanger an individual's health (e.g., exposure to toxic gases or sound level beyond a certain threshold). Therefore, measuring the environmental elements can protect individuals' health as well. In this work, we emphasize that a new approach and strategy in wearable devices, multiparameter monitoring, miniaturization, sensor integration, data fusion, and system adoption within the Internet of Things (IoT) is necessary according to today's demands.
