摘要： A system and method for creation and function of an advanced prosthetic hand includes: a base palm, comprising the primary body of the prosthetic hand; a set of actuating digits, wherein each actuating digit is connected to the palm; a sleeve, connected to the palm, providing an interface; a sensor system, comprising sensors integrated on a subset of the set of actuating digits; and a feedback system, connected to the sensor system enabling sensory feedback from the sensor system. In preferred variations, the base palm comprises, at least partially, a carbon-fiber shell. The system may further include a set of water sealing elements integrated into the prosthetic hand. The system functions as a hand prosthesis with actuating digit and hand components.

摘要： A system and method for a prosthetic assembly that includes a first prosthetic component, comprising a prosthetic hand base; a set of second prosthetic components, comprising a set of prosthetic fingers, and a set of actuating systems, wherein one actuating system connects a pair of distinct prosthetic components, enabling actuation of one prosthetic component with respect to the other. Each actuating system, from the set of actuating systems, includes a linkage and a sensored brushless motor; wherein the sensored brushless motor comprises a brushless motor, a field oriented control system, a rotary encoder, and a gearbox.
