I am looking to enter grad school to improve my employment prospects. Does anyone have any recommendations of universities where I could focus my education on prosthetic limb design?
If you want to get employed to design prosthetic limbs, there are NOT many companies. Then it might be the best before you decide any further to ask each of these if you could come and do a voluntary internship for 2-4 weeks to observe and learn how their production process works.
Maybe you find that some or even a considerable amount of technology is actually some OMD manufacturing produced mass ware that is imported from Far East.
The company list you could check out might include RSL Steeper, Centri, Hosmer, Utah Arm, Touch Bionics and Otto Bock.
