Smart textiles using fabric-based sensors to monitor gesture, posture or respiration have been exploited in many applications. Most of fabric-based sensors were fabricated by the techniques including coating piezoelectric materials on a fabric and directly knitting conductive fibers into fabric. In this work, the possibility of generating electric potential by coiled fibers with core-shell structure is studied. The hypnosis is that the electric field or potential could be created between the electrodes of the metal wire and the metal coated on the surface of coiled fiber, when it was squeezed or pressed by supplied forces. In order to investigate the hypnosis, the polyvinylidene fluoride (PVDF) fiber with the core of metal wire was used as the model, and the polarity theory was applied to explain the capability of energy conversions. Moreover, the piezoelectric fabric was designed and the possibility of using this fabric to make textile sensor was investigated.
