The real problem is not that we can't mimic the hand's mechanical properties, it is that current on the market prosthetics use control systems that are essentially unchanged since the 1960s (there are slight improvements but no huge leaps). Current control systems can't mimic the hand's motions, so building hands as human-like as possible isn't done.
I came up with a design for a control system that looks very promising on paper as a replacement for the current mechanisms. Whether this can hold up to rigorous real-world tests remains to be seen. I may use this project as a Master's project for reasearch; I will be going on to grad school in the fall of 2002.
