The ray itself isn't what they`re testing.
They`re actually testing the artificial muscles used to control it. It`s a type of plastic that can contract and release when an electrical charge is applied to it.
We`ll all be seeing a lot more about this material in the next year or two.
There are actually plans to make more realistic artificial limbs out of it.
