The prosthetic arms will be soon in the market to help
amputees. The revolutionary new invention is invented by DARPA (Deka Research
and Development Corp.)
It has capability of translating signals of patient’s
muscles into complex motions. Labeled the LUKE (Life under Kinetic Evolution)
arm by Mobius Bionics, a leading medical device maker and will be marketed by
Universal Instruments Corporation.
The LUKE arm’s central control technology consists of
electromyogram (EMG) electrodes which are designed to catch electrical signals
from the patient’s muscles. The new invention is able to translate signals
about how much movement, control and strength to the arm.
The LUKE arm has number of benefits to amputees which can
reach overhead and behind the back by its well-designed powered shoulder joint.
It is strong enough to lift a bag of groceries and a glass of water with safe
distance without spilling. The hand includes four motors that can hold heavy
items and even hold an egg without dropping and breaking.
The LUKE arm has a sensor that also returns the information
to the patient about how firmly any device is grasped. The wireless foot
mounted inertial measurement sensors are used to control the arm.
The LUKE arm has tested on nearly 100 amputees and has been
developed by DARPA, the U.S Veteran administration and private companies.
