Micromachine
Microscopic technology at a scale of one millionth of a millimeter, capable of redesigning and reconstructing the human nervous system as well as our world. This ultra-minuscule technology has led to various applications such as cyberbrains, cybernetic bodies, vaccines, and even lethal bioweapons. The world of “Ghost in the Shell” began with the technology that allowed us to fully understand the activity of the brain and spinal nervous system using micromachines.
