    摘要: A system and method for affecting the function of a mammalian ear. The system and method uses an oscillating magnetic field to move nanospheres comprised of single-domain nanoparticles. In a preferred embodiment a receiving assembly detects sound waves and transmits the sound waves to a processor. The processor drives an electromagnetic coil in response to the detected sound waves. The electromagnetic coil transmits a signal that causes vibration of the nanoparticles and the tissues within which the nanoparticles are implanted.
