(2) Title:

 Highly Flexible and Conformable ZnO/FeGa Magnetoelectric Heterostructures for Skin Wound Healing

(3) Research Idea:

To address the invasiveness of conventional electrical stimulation for wound repair and weak magnetoelectric coupling of existing magnetoelectric materials restrained by clamping effect, this work designs skin-conformable flexible ZnO/FeGa magnetoelectric heterostructures. It realizes wireless conversion from magnetic field to electric field via magnetoelectric coupling and explores its regulation on skin-related cellular behaviors in vitro for wound healing.

(4) Material Development:

① Materials: PDMS flexible substrate, ZnO piezoelectric nanosheets, FeGa magnetostrictive layer with Au/Ti composite electrode
② Functions: It conforms to irregular skin surfaces and wirelessly generates electric fields under low-frequency alternating magnetic field. With favorable biocompatibility, it modulates cell differentiation, collagen secretion and cell migration.
