1. A system for an advanced prosthetic hand comprising:
a base palm, comprising the primary body of the prosthetic hand;
a set of actuating digits wherein each digit is connected to the base palm and where each actuating digit comprises:
a bone structure, and
malleable skin layer that is overmolded around the bone structure;
a sleeve, connecting the prosthetic hand to a prosthetic wearer;
a sensor system, comprising a set of sensors integrated on a subset of the set of actuating digits, wherein at least one sensor of the set of sensors is integrated into a bone structure, wherein the set of sensors comprises a set of Hall effect sensors and a set of magnets, wherein each magnet of the set of magnets is encased in the skin layer and displaced and aligned with a Hall effect sensor of the set of Hall effect sensors; and
and a feedback system, connected to the sensor system enabling sensory feedback from the sensor system.
