Wearable system is a proper solution for rehabilitation and instrumentation applications for human daily activities. Recently, several researches are concentrated on this technology significantly because of new progress in sensors and fusion sensors. In the near future, wearable and ambulatory devices will be used considerably in biomedical applications. In this study, we reviewed some methods about wearable measuring system then introduced and designed innovative wearable clothing for this purpose. Some specifications and advantages of our system in comparison with relevant researches are; using painted sensors that 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 trunk movements 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 the positions of textile sensors on the body. Furthermore, an electronic board is developed for data acquisition and transfer data to computer real-time. Finally, the wearable clothing for ambulatory purposes was manufactured and also different methods for the system calibration have been presented.
