| Abstract [eng] |
Polyvinylidene fluoride (PVDF), a well-known piezoelectric polymer, has emerged as a promising material for advanced energy harvesting and sensing applications due to its flexibility, durability, and exceptional piezoelectric properties. This study investigates the use of PVDF sensors for converting ambient mechanical energy into electrical power, addressing key challenges in scalable and sustainable energy harvesting systems. A specially designed energy harvesting circuit was developed, incorporating a rectifier, energy storage capacitors, and an LED load to demonstrate practical energy utilization. Previous research highlights the capability of PVDF-based systems in biomechanical energy capture and self-powered sensing [1]. Furthermore, hybrid composites of PVDF with advanced materials, such as reduced graphene oxide, have been shown to enhance energy conversion efficiency [2]. This work establishes PVDF as a versatile piezoelectric polymer, paving the way for innovative solutions in energy harvesting and sensing technologies for diverse applications [3]. [...]. |
