BaTiO₃-Based Piezoelectric Smart Textile for Energy Harvesting and Touch-Triggered Electroluminescent Display

Abstract

Smart textiles, which rely on biomechanical energy gathered from the environment, offer the most self-powered sensing and performance in interactive displays. The design, manufacture, and testing of textiles with multilayer piezoelectric made of polyvinyl siloxane and barium titanate (BaTiO₃) are demonstrated in this work. A silver-coated yarn is also utilized for the exterior functionalization, electric poling, and dip-coating with BaTiO₃/vinyl-siloxane paste at three distinct ceramic volume loadings (30%, 50%, and 70%) to enhance the tip-enhanced piezoelectric response of the yarns. Data indicate that electric signals produced by the cotton tap are amplified using an electronics unit equipped with a comparator and a charge amplifier. Reflect that data to light the EL-based PVDF yarn. Such a system could efficiently produce touching-triggered luminescence with apparent perspective in the development of self-powered wearables used for sensing and visual feedback. The demonstration and achievement of the yarns' piezoelectric performance served as the inspiration for both performances and displays; open-circuited voltage concepts are roughly 1.5V under 1N of a tip, and EL permits performance exceeding 95%. Sustainable evaluation because it has enabled the recall of touch to light operation standards, resulting in over 10,000 tap cycles and few or no washing cycles. The efforts are showcased in the lead-up to the development of flexible-line-piezo pressure devices that enabled wearable, effective monitoring, human-machine collaboration, and stable, self-operating, interactive clothing.
