BREATH AND HEAD TILT CONTROLLED PROSTHETIC LIMB

摘要

In alternative embodiments, provided is an internally powered prosthetic limb and method for controlling same, offering hands-free control of a prosthetic limb. The internally powered prosthetic limb controlled by an input control device, comprising: a breath inlet configured to receive air pressure exerted from a user's mouth to be converted into a first electronic signal, wherein the first electronic signal is proportional to the exerted pressure; a motion sensor configured to sense tilting of the user's head and operable to convert the user's head tilting motion into a second electronic signal, wherein the second electronic signal is proportional to the user's head tilting motion; and a processor in communication with the breath inlet and the motion sensor, the processor operable to convert the exerted air pressure into the first electronic signal and further process the first electronic signal into first positional data for transmission to a plurality of digit-actuators in the prosthetic limb, the processor further operable to process the second electronic signal into second positional data for transmission to a wrist-actuator in the prosthetic limb; wherein the plurality of digit-actuators in the prosthetic limb can be controllably actuated in proportion to the air pressure exerted by the user, and the wrist-actuator can be controllably actuated to rotate in proportion to the head tilting motion of the user.
