Magnetoelectric properties and magnetomechanical energy harvesting from stray vibration and electromagnetic wave by Pb(Mg_1/3Nb_2/3)O₃-Pb(Zr,Ti)O₃ single crystal/Ni cantilever Available to Purchase

Magnetoelectric (ME) rectangular unimorph cantilever beam structures of piezoelectric Pb(Mg_1/3Nb_2/3)O₃-Pb(Zr,Ti)O₃ (PMN-PZT) single crystal on magnetostrictive Ni plate was designed with ⟨001⟩ and ⟨011⟩-cut crystallographic directions and investigated their ME response and mechanical vibration based energy harvesting behavior. Both magnetoelectric (ME) voltage coefficient (α_ME) and mechanically harvested power output was found to be strongly dependent on the crystallographic cut directions of PMN-PZT single crystals. The maximum α_ME and power output of 7.28 V/cm Oe and 1.31 mW was observed for ⟨011⟩ PMN-PZT/i unimorph ME structure at resonance mode under 0.7 G acceleration. The ⟨011⟩ PMN-PZT single crystal showed that in-plane anisotropic behavior, i.e., d₃₁ and d₃₂ significantly affect to the magnitude of α_ME and harvested power output.
