/bjnano.11.148 Abstract The tracking of body motion, such as bending or twisting, plays an important role in modern signlanguagetranslation. Here, a subtle flexible self-powered piezoelectric sensor (PES) made of graphene (GR)-doped polyvinylidene fluoride (PVDF) nanofibers is reported. The PES exhibits
correlation between temperature and signal can be used to avoid burns. The integrated sensing system based on multiple PESs can accurately recognize the action of each finger in real time, which can be effectively applied in signlanguagetranslation. PES-based motion-tracking applications have been
effectively used, especially in human–computer interaction, such as gesture control, rehabilitation training, and auxiliary communication.
