| Abstract Scope |
This research addresses health concerns associated with lead-based perovskite oxides in sensing and actuating technologies by developing novel, lead-free composite materials. The study enhances the electroactive properties of PVDF-TrFE through strategic incorporation of BaTiO3 and Ti3C2 MXene, aiming to match the effectiveness of traditional piezoceramics while maintaining biocompatibility. By varying MXene content (1-5%) and keeping BaTiO3 constant at 30%, the research optimizes the composite's electrical and piezoelectric characteristics. Impedance analysis and piezometry quantify dielectric constants, capacitance, impedance, and piezoelectric properties across 20 Hz to 10 MHz, benchmarked against pure PVDF-TrFE and PVDF-TrFE/BaTiO3 samples. Scanning Electron Microscopy examines microstructure and porosity, exploring correlations with electrical performance. Initial findings indicate enhanced sensitivity and electron transport capabilities, suggesting potential applications in medical wearables across diverse frequency ranges. This study contributes to the field of biocompatible electroactive materials, offering alternatives that balance safety, flexibility, and performance for next-generation wearable health technologies. |
