Bionic arm – level 1
A bionic arm is not a real arm. It is mechanical. It works almost as well as a real arm. It changes a person´s life. A person does not need so much help from other people if he has this arm. He can play games or ride a bike. He can tie his shoes.
Campbel Arid gets his bionic arm in 1998. He is the first person in the world who gets it. His arm weighs 1.8 kilograms. It uses a battery.
Now the technology is changing very quickly. Today´s bionic arm reads signals from a person´s muscles. Scientists believe that the technology will change soon. New technology will read a person´s mind.
Difficult words: mechanical (something that looks like or works with help of a machine), signal (an action or sound which shows that something exists, or it gives information about something), muscle (a part of a body which helps somebody move).
You can watch the original video in the Level 3 section.
