  7. Abstract:
  8. Measurement of human movement during work, sport as daily activities has important effects for rehabilitation and biomechanics experts.
    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 textile sensors that are manufactured through nano electro active polymer technology, low weight, low price, applicable for daily activity, 3D complexy trunk movements was measured accurately and non-invasive. Twelve 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, some Electronic Boards and Data Logger were developed for data acquisition and data transfer to computer real-time and offline. Finally, the wearable clothing for ambulatory purposes was manufactured and also different methods for the system calibration have been presented. The movement were measured with accuracy 0.5-1 degree and 2.7 degrees for discerete and mixed movements respectively
