Design and Prototyping of Wearable Measuring System for Trunk Movement Using Textile Sensors

Wearable system is a proper solution for rehabilitation and instrumentation applications for human daily activities. Recently, several researches are concentrated on this technologysignificantly because of new progress in sensors and fusion sensors. In the near future, wearable and ambulatory devices willbe used considerably in biomedical applications. In this study, we reviewed some methods about wearable measuring system thenintroduced and designed innovative wearable clothing for this purpose. Some specifications and advantages of our system in comparison with relevant researches are; using painted sensorsthat are manufactured through nano electro active polymer technology, low weight, low price, applicable for daily activity,three dimensional detection of human body movements and noninvasive. We utilized textile sensor to measure the trunkmovements in three dimensions. Twenty textile sensors were attached on the clothing in this version of system. In addition to wearable system, clothing was prepared in order to determine thepositions of textile sensors on the body. Furthermore, an electronic board is developed for data acquisition and transferdata to computer real-time. Finally, the wearable clothing for ambulatory purposes was manufactured and also differentmethods for the system calibration have been presented
