How do prosthetic hands, arms, legs, etc. work and how is the user able to control it without it actually being apart of their body?
In: Technology
it depends on the type of prosthetic for how they attach, some are just form fitting attached to the body, others use straps, other screw or snap onto parts that are actually implanted to the body, there is a wide variety.
for being able to control a prosthetic their are a couple different ways to, and im going to assume you mean control like opening/closing a hand. many real simple prosthetics don’t even have this moving ability so it is just a function working with what you got.
Others use physical buttons/levels to activate the hand movement. for example someone who lost an arm may move their shoulder in a specific way that pushes a button that causes the hand to open/close.
Some prostethics are now even advancing to the point where they can be triggered by sensing nerve impusles, so a person could just think about opening their hand and open the prosthetic, I am not sure how common these are or how far this has advanced in the past couple years so google might be a friend.
