Final answer:
Artificial Intelligence is not a focus area of the MIT Center for Extreme Bionics; instead, they emphasize Biomechanics, Neural Engineering, and Tissue Engineering to enhance human capabilities.
Step-by-step explanation:
The area of research not being worked on by the MIT Center for Extreme Bionics is Artificial Intelligence. The MIT Center for Extreme Bionics focuses on advancing the field of bionics and related scientific areas to enhance human capabilities. The areas they are specifically known for include Biomechanics, the study of the structure and function of biological systems, Neural Engineering, which involves developing interfaces between the nervous system and artificial devices, and Tissue Engineering, which is the use of a combination of cells, engineering, and materials methods to improve or replace biological tissues.
