Abstract
The design of strain sensor made from conductive fabrics (CF) requires precise characterization prior to their intended use. However, the electrical signals produced by the direct resistance measurements of CF are irregular and have high deviation which affects its performance as a wearable strain sensor. In this paper, we explore an alternative design, where the electromechanical property of a CF is characterized under the application of a small constant current. The result showed an improvement in the maximum standard deviation of its electrical signals from 0.2 to 0.06 for a commercially available CF. Apart from enhancing the reliability of the commercial CF, we also found that a variety of strain axes, besides its principal course axis, can be used in the design of the fabric sensor.
