What is a cochlear implant?
A cochlear implant is a medical device that is placed into the head behins the ear of a deaf person. When it is used with a microphone and speech processor it stimulates the auditory nerve allowing the person to hear.
Many people with hearing loss can use hearing aids to help them hear but people with severe hearing loss or deaf hearing aids don’t work. These people may use the cochlear implant
The cochlear implant replaces the function of the entire ear. It uses a microphone that stimulates the auditory nerve using electricity to allow the brain to perceive sound.
The number of people that have received this surgery has grown to over 27, 000 with more than 13, 000 of these are children.
Who invented the cochlear implant?
Professor Graeme Clark of the University of Melbourne was the creator of the world’s first implant and is considered by many to be the father of the cochlear implant.
In 1967 Clark embarked on his dream to help the deaf hear. As a PHD student at the University of Sydney, he reviewed the research to investigate whether a single or multi channelled cochlear would be possible to make.
He believed that implants on humans should not be done until basic testing on animals was performed. He experimented on animals for 10 years trying to stimulate their auditory nerve and struggled on University Grant Funds.
Range Technologies used in the development of Cochlear implants
1. The ten-layer, double sided circuit board which was the main body of the processor, it is mounted with six circuit components as well as capacitors, transformers, resistors and other components.
2. A pick and place machine is used to automatically place and solder components t the gold pads on the board.
3. The circuit board, which is made up of flexible and rigid parts.
4. The control panel, with buttons and LCD window is assembled onto the moulded plastic case
