ARTIFICIAL SENSORY EPITHELIUM |
| 摘要 |
An artificial sensory epithelium (1) to be embedded in a cochlea (301) of a patient includes a piezoelectric film (2) and multitude microelectrodes (3), (3), . . . arranged on the cochlea. The piezoelectric film is arranged along a basilar membrane (306) in the cochlea. A portion of the piezoelectric film that corresponds to a portion of the basilar membrane that is induced to vibrate by sound waves coming from outside the cochlea vibrates. A microelectrode of the microelectrodes that is arranged on the portion of the piezoelectric film provides electric stimuli to spiral ganglion neurons (311). The artificial sensory epithelium preferably includes a support member (4) configured to support the piezoelectric film and be fixable in the cochlea. |
