This paper presents initial research into the tracking of arm movements using a foam-based pressure sensor to record dynamic forces present in a worn garment structure in motion. A soft, washable polypyrrole-coated foam sensor was used in 4 discreet locations around the armscye, and resistance changes were recorded for all 4 sensors as the subject performed 4 arm movements. This study is a first step in the exploration of the utility of foam-based sensors in the recording of body movements through garment response. The results presented here are preliminary; however they do indicate that the responses of this sensor in these locations can adequately indicate upward, downward and forward arm positions. Further work is required to model the more complex garment interaction experienced during backward arm movement, and the effect of garment structure on sensor response.
