Wearable Spine Postural Monitoring Embedded System for Occupational Health in Sitting Position

Abstract

This document presents the design and construction of an embedded system to alert the position of the back in order to improve the occupational health of users who remain long in sedentary positions. The proposed system is an alternative to monitor and alert the spine posture of people whose daily activities demand to remain long period of time in a sitting posture, in order to avoid problems in the medium or long term. The wearable system consists of a flexible resistive sensory surface that molds to the shape of the spine in order to measure its position. The sensors are located in a vest that is easy to use to improve the comfort of the user. The system uses a Bluetooth BLE communication to send the data sensed to a mobile device, which monitor and save the position of the user and be able to alert if it is in an incorrect position that can affect their health. In addition, the data is saved in an online database, creating a history of postural compartment of each user. The app also suggests exercise routines such as active pauses to improve worker performance that reduces work fatigue, improves joint mobility, prevents and reduces stress, and reduces the risk of occupational diseases.
