摘要

Numerous novel technologies, including self-powered implanted sensors and wireless sensor networks (WSNs) have evolved over the past decade. Due to the complications related to charging and maintaining batteries, these devices generally include a continuous power supply to operate consistently and safely. A viable solution may involve piezoelectric energy harvesting derived from vibrations produced by artificial technology, human motion and environmental factors. This paper presents the inaugural integration of piezoelectric polyvinylidene fluoride yarn-braid within the FRPC structure. The developed smart composite demonstrates its multifunctional capabilities, encompassing structural reinforcement, vibration attenuation, and energy harvesting. Testing subjected to cyclic loading circumstances of 5 to 22.75 Hz produces a power density of 3.1 mW/cm³ and an AOV of 3.8 V when strains are below 0.27%. The utilized axial corona poling and coreless radial methods result in significant improvements in the beta-phase content and crystallinity percentage of the polyvinylidene fluoride fibers upon reception with increases of 5.56% and 60%, respectively.
