Remarkable that he managed to make the hand by himself! It's a great feat!
Should it be "mechanical" rather than "Bionic"? I saw differing definitions on the term "bionic"
"having particular physiological functions augmented or replaced by electronic or electromechanical components"
It seems that the hand is mechanical with no electronic parts. Not very sure though. It seems that Merriam Webster has 2 definitions:
1 : of or relating to bionics
a : having normal biological capability or performance enhanced by or as if by electronic or electromechanical devices
b : comprising or made up of artificial body parts that enhance or substitute for a natural biological capability
Or the keyword is natural biological capability? Let me know which is correct...
