For example if i lost my arm or someone loosing there leg. Do you think technology will ever come to a point that they will replace it with some machinery; which will it seem as it were my normal arm.
The nerve interface, especially with sensation, would always prove a challenge. There may be better luck in technology that would mimic what some salamander can naturally do: grow back the limb.
a new techonology must be developed first. It has to deal specifically with not only the biomechanics of the human muscoskelatal system, but also the physiodynamics involved in getting signals to fire those muscles properly. this field could be called biomimetics, and it's main focus in it's infancy should be nanoinnervation, where an electronic interface is provided by bridge circuits comprised of 1/2 biological cellular base circuits, and the other 1/2 completed to the cybernetic limb by means of a bioreactive feedback circuit, composed of an input CPU, and BFC controller, and finally a signal interpreter and output bus, generally running in conjuntion with a gate biological/electronic ( cybernetic) diodic device. ( think thin film quartz resistance feedback potentiometers that allow the BFC to make decisions on bioproprioception using the gate circuit as input/feedback loop.
Of Course!! We've already seen the beginnings of that with robotic limbs and things like that. Science will eventually perfect a way to replace lost limbs with machinery. It's just a matter of time...
I agree with Maria. It will most definitely come to pass. The biggest obstacles right now are the nervous system, and understanding how it issues commands to the body. Most current technologies use muscle triggering. For example, all of your muscles work together. If you move one part of your body, muscles in adjoining body parts tense up in specific ways to help counter momentum to give you better control. Using those facts, scientists can design body parts that read and respond to those trigger movements. It's not perfect, but it does work to an extent. To be true limb-replacement, the nervous system will need to be better understood.
