The need for flexible and transparent smart materials is leading to substantial advances in principles, material combinations, and technologies. Particularly, the development of optically transparent magnetoelectric (ME) materials will open the range of applications to new directions such as transparent sensors, touch display panels, multifunctional flat panel displays, and optical magnetic coatings. In this work, a flexible and transparent ME composite is made of magnetostrictive Fe 72.5 Si 12.5 B 15 microwires and piezoelectric poly(vinylidene fluoride‐trifluoroethylene). The high magnetostriction of Fe 72.5 Si 12.5 B 15 (35 ppm) enables superior ME voltage response (65 mV cm −1 Oe −1 ) obtained at the critical longitudinal magnetic field equating the transverse anisotropy (14500 A m −1 ) on the external shell of the microwire.
