MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511117760 A) filed by Baba Farid College Of Engineering And Technology; and Baba Farid College, Bathinda, Punjab, on Nov. 26, 2025, for 'interpenetrating polymer network composite with multiferroic ceramic for magnetic field sensor.'
Inventor(s) include Jaswinder Pal; Anupinder Singh; Sunil Kumar; Sajan Masih; Vishal Arora; and Amritpal Singh Nindrayog.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The disclosure relates to a polymer-ceramic composite (100) comprising an interpenetrating polymer network (IPN) (102) of polyurethane (PU) and polymethyl methacrylate (PMMA) containing a multiferroic ceramic component (104) dispersed therein. The ceramic component (104) is a perovskite-type oxide exhibiting coupled ferroelectric and magnetic ordering, selected from rare-earth ferrite-titanate solid solutions or equivalent multiferroic oxides. Under a magnetic field, the magnetostrictive response of the ceramic component (104) induces mechanical stress through the IPN (102), producing electrical polarization and measurable magnetoelectric voltage output. The disclosure further provides a method (200) for preparing the composite by in-situ polymerization, dispersion of the ceramic component (104), and controlled curing to obtain flexible, thermally stable sheets useful for magnetic field sensing, energy transduction, and magnetoelectric applications."
