This mind-controlled prosthetic arm just got FDA approval. The DEKA arm is the first of its kind to get approval from the FDA.
The bionic arm is the result of almost eight years of work from DARPA, the US Defence Department's advanced research agency, who were looking for a better answer for amputees. Designed by a company founded by Segway inventor Dean Kamen, the mind-controlled prosthetic is roughly the same weight and size as a regular human arm.
The fake limb is controlled by electromyogram electrodes placed on the remaining portion of the human arm. The sensors collect information from the upper arm and communicate what kind of movements or manoeuvers the arm wants to do to a computer inside the prosthetic.
