Question: could you find a substitute for muscles in the body

Keywords: , ,

  1. There are already plenty of robotic substitutes. Our muscles are basically just motors that work by shortening. So motors are the most basic substitute, and fancy plastics that bend or shorten when you electrify them are are more complex substitute.

    Currently there isn’t a substitute that can be implanted in the human body, this is probably just a matter time. However, there are plenty of robotic prosthetics that attach to the outside of the body to substitute for or assist muscles in disabled people. There are also robotic limbs for amputees. These robots are not so popular yet because the are quite slow and very expensive.


  2. I’d say – what Lee said! I agree that we haven’t discovered a substance that can be used as a substitute for muscle yet, but it is only a matter of time. The substance would have to be very strong yet flexible. It would also have to be produced under sterile conditions if you wanted to implant it into the human body so that it didn’t cause any immune reactions. These days you can think up or design a substance and try to synthesise it in the lab. You’d then test it to see if it had all the properties you were after, non-toxic and could be produced quite cheaply.
