Paragraph starter

The development of magnetoelectric (ME) composite materials offers significant potential for energy harvesting and sensing applications. Research indicates that the ME effect is not monolithic but comprises distinct magnetostrictive and magnetoactive contributions. Crucially, the relative influence of these contributions can be modulated by controlling the orientation of magnetic nanoparticles within a piezoelectric polymer matrix. This suggests that designers can leverage controlled particle alignment as a key strategy to optimize the functional performance of ME composites, tailoring them for specific energy conversion or sensing requirements.
