Cyborg anatomy
Fuel cell
Fuel cells were researched and developed by international collaboration, and became a commodity in the early decades of the 21st century. From conventional hydrogen and chemical fuel cells to nuclear power cells designed for military purpose, they all had the capability to power a cyborg at least during a usual workday, but usually several days or rarely entire weeks.
Cyberbrain
A network of synthetic (non-organic) neurons copying the structure of the human brain, resulting in an artificial entity. The cyberbrain is extended by memory, processing and other optional and required modules. Both the synthetic neurons and the A.I. (structure of the brain) were developed by one of the greatest scientists and visionary of Humanity, Shimabukuro Saburo.
Synthetic muscles
Developed by the United States based Biodynamics Laboratories. The artificial muscles operate the same way as human muscles but are completely synthetic (containing no organic elements) and have 10 to 50 times the strength of a human muscle.
Skin and other human-like features
Optional elements which are only added in case of androids.
Other
Skeleton, skull, armor (optionally), hull, sensors and internal systems are also necessary (but usual) parts of a cyborg.
