MIT Media Lab's AMI Project: Restoring Proprioception in Prosthetic Limbs

Crisped on the outside, thoughtful enough on the inside.
Summary
The article describes the Agonist-antagonist Myoneural Interface (AMI) project from MIT Media Lab, which aims to restore proprioception in prosthetic limbs. Unlike conventional prosthetics that don't provide feedback to the nervous system, AMI technology enables amputees to feel the position, speed, and torque of their prosthetic joints without visual confirmation. The project focuses on creating a more complete prosthetic control experience by re-establishing the natural sensory feedback loop that allows humans to precisely control body movements.
Key quotes
· 5 pulledHumans can accurately sense the position, speed, and torque of their limbs, even with their eyes shut.
This sense, known as proprioception, allows humans to precisely control their body movements.
Today's conventional prosthetic limbs do not provide feedback to the nervous system.
Because of this, people with amputated limbs cannot feel the position, speed, and torque of their prosthetic joints without looking at them, making it difficult to control their movement.
In order to create a more complete prosthetic control experience...
