Ear
Some patients suffering from deafness or severe hearing loss
can find help with cochlear (inner ear) implants. One such
device consists of electronics placed in a ceramic housing
under the skin behind the patient's ear. Sounds transmitted
from a mic outside the body to the internal electronics are
then shuttled through wires into platinum electrodes implanted
directly in the patient's inner ear. These electrodes
stimulate nerve fibers to produce sound sensation to the
brain.
