Report on the bionic ear and why it is made out of the materials it is made from.

Bionic Ear The bionic head (cochl spike heel implant) is an artificial audition device designed to help hearing impaired and deeply deaf people. separate of the bionic ear atomic number 18 participate into the skull other move are faint-hearted on the out expression of the body, the interior(a) par t is called the head set. The headset consists of a 22-channel stimulator that is held in a titanium capsule with platinum electrodes which is inserted into the shell-like structure in the inside(a) ear known as the cochlea. A ball electrode is implanted downstairs a muscle near the ear. The speech processor is outwardly worn, it can be worn bathroom an ear or held in a pocket. The coil is held in plaza against the grate by a magnet and the mike is worn behind the ear. Speech and other sounds are picked up by the mike and are sent to the speech processor. The speech processor changes sounds into ball over signals that are sent through a cable to the transmittanc e coil. The coil sends the signals through the skin to the implant which transforms the signal to galvanising pulses. The pulses pass from the electrode array and stimulate hearing nerve fibres at bottom the cochlea.

It is not possible to make the sounds heard by the bionic ear completely natural, and this is because in the implant their are still 22 electrodes that are replacing the function of thousands of hairs-breadth cells in a normal hearing ear. The materials used in the bionic ear are platinum and titanium, below is rough nurture on the two elements. Platinum Symbol: Pt Atomic Number: 78 Atomic Weigh t: 195.075(s) melt down show up: 2041.4 K ! Boiling Point: 4098 K Platinum is soft, dense, ductile metal that is rattling resistant to corrosion. Because it is very life-threatening electricity conductor and is very... If you want to get a rich essay, order it on our website: OrderCustomPaper.com
