Desenvolvimento de sensor de angulação com acelerômetro para a avaliação postural da coluna

Abstract

In daily life, posture is often relegated to a secondary concern, especially during the execution of tasks or activities. In the current context, where more and more people are working remotely and spending long hours sitting, there has been an increase in the development of pathologies and damage to the spinal column. With this in mind, this work aims to develop a prototype capable of taking measurements and monitoring a person’s spinal position over a specific period, using gyroscope and accelerometer sensors. These sensors capture the individual’s positioning information, which is then processed by an algorithm to evaluate postural behavior and the duration of exposure to poor posture. The study is based on a literature review and the adaptation of existing works, aiming at the construction of a prototype and the validation of measurement accuracy. The results show that it is possible to reliably obtain a person’s spinal position over time by applying the solution and the concepts developed in this project. Thus, this work aims to contribute to the dissemination of technology and improvement of technological solutions focused on ergonomics.
