Prosthetics & Genetics
Modern Medical Technology
This paper focuses on two types of medical technology: genetics and prosthestics.
Genetics - The science of heredity, dealing with resemblances and differences of related
organisms resulting from the interaction of their genes and the environment.
Prosthetics - A device, either external or implanted, that substitutes for or supplements a missing or defective part of the body.
In the past decade, smart prostheses have been invented. A smart prosthesis connects to the brain or central nervous system. For example, a cochlear implant contains a microphone that receives sound waves from behind the ear. The microphone then converts the sound waves into electrical impulses and sends them through a thin wire implanted in the cochlea. The brain then identifies the sound from prior knowledge.
In 2007, researchers created a bionic eye for the blind. Inside the bionic eye there is a tiny camera that takes pictures.The picture is then transmitted into electrical impulses which transfers the image to the brain. The brain cross references the image with past memories and objects until identifying the right image. Electrodes help replace dead or damaged cells in the eye helping to restoring sight which are a result of the bionic eye.
For many losing a hand or arm could mean the end of doing something they love. However, with new technology scientists have been able to develop an arm that people can control with their brain! When you want to perform an action your brain sends an impulse across your skin, nerves, and muscles. The Myoelectric Hand has sensors that pick up the impulses and then perform the action. Each electrical impulse is unique so all you have to do is think about it! This was a revolutionary invention that will help better the lives of many in the future.
