Multifunctional nanosensors based on piezoelectric and magnetoelectric sandwich structures

This study investigates the vibration and buckling of three-layer sandwich nanoplates made from piezoelectric and magnetic materials. This study seeks to determine the fundamental frequencies of four nanosensor combinations made from different materials. This work uses piezoelectric and magnetic materials such PZT5H, BaTiO3, and CoFe2O4 to test nanosensors' electrical and magnetic field sensitivity. The system of equations was generated using Hamilton's variational principle and solved analytically using Navier's method. The findings show that material type and layer topologies significantly affect the natural frequencies of these sensor devices. This study improves multifunctional nanosensor design by analyzing electro-mechanical and magneto-mechanical interactions. © 2026 Taylor & Francis Group, LLC.
