1. A wireless electromagnetic receiver comprising:
a first device configured to be magnetized based on an electromagnetic field, generate mechanical oscillation based on the magnetization, and generate variable tension based on the mechanical oscillation wherein the variable tension generates variable magnetization; and
a second device configured to transfer voltage oscillation as power to a load, wherein the variable magnetization induces the voltage oscillation at an end of the second device,
wherein a size of the first device formed by a magnetostrictive material is inversely proportional to a resonance frequency of the first device, and
wherein the second device surrounds a portion of the first device.
