MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641043213 A) filed by Pentakota Murali; Prof. Koona Ramji; Prof. V. V. S. Prasad; and Andhra University, Visakhapatnam, Andhra Pradesh, on April 4, for 'a method and system for fabrication of high-quality barium calcium zirconate titanate (bczt) nanofibers using electrospinning for piezoelectric and energy-harvesting applications.'
Inventor(s) include Pentakota Murali; Prof. Koona Ramji; and Prof. V. V. S. Prasad.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses an optimized method and system for the fabrication of high-quality Barium Calcium Zirconate Titanate (BCZT) nanofibers using the electrospinning technique. A precursor solution comprising barium acetate, calcium acetate, zirconium nitrate, titanium isopropoxide, and polyvinylpyrrolidone (PVP) at an optimized concentration of 0.1 g per 20 mL is electrospun at 13 kV, a flow rate of 1.2 mL/hr, and a needle-to-collector distance of 13 cm using a rotating drum collector. Post-processing by drying and calcination at 700 C for two hours yields crystalline BCZT nanofibers with an average diameter of approximately 200 nm, smooth morphology, and minimal bead formation. SEM characterization confirms superior fiber uniformity. Dielectric measurements demonstrate piezoelectric coefficients (d33) of 8.8 pC/N and 9.4 pC/N, confirming excellent piezoelectric performance. The invention provides a scalable, lead-free alternative to PZT-based materials for sensors, actuators, and energy-harvesting applications."
