The prosthetic device may include a flexure cut and/or a sensor to detect movement in accordance with a degree of movement. In an embodiment, the sensor may be disposed within the flexure cut. Other embodiments include at least one wire configured to connect a sensor located in a distal portion to a proximal portion, while annularly traversing a joint. ## Claims ### Claim 1 A prosthetic device comprising: a flexure cut extending from a surface of the prosthetic device towards an inner part of the prosthetic device; a sensor located in a distal portion of the prosthetic device to detect movement in accordance with a degree of movement wherein the sensor is disposed within the flexure cut; and at least one wire configured to connect the sensor to a proximal portion of the prosthetic device, wherein the at least one wire annularly traversing a joint of the prosthetic device. ### Claim 2 (depends on 1) The prosthetic device of claim 1, further comprising a finger structure, wherein the flexure cut is disposed within the finger structure. ### Claim 3 (depends on 2) The prosthetic device of claim 2, wherein the finger structure comprising an outer surface, a first dissected surface and a second dissected surface that define the sides of the flexure cut, wherein the sides of the flexure cut extend linearly inward from an outer surface of the finger structure. ### Claim 4 (depends on 3) The prosthetic device of claim 3, wherein the flexure cut traverses through the finger structure in a curvilinear manner. ### Claim 5 (depends on 1) The prosthetic device of claim 1, wherein the sensor is configured to measure movement in accordance with the at least one degree of freedom. ### Claim 6 (depends on 5) The prosthetic device of claim 5, further comprising a processor disposed in the proximal portion; and a joint configured for annular motion, the sensor disposed within the distal portion, wherein the at least one wire connecting the sensor in the distal portion to the processor in the proximal portion, wherein the at least one wire is configured to circumvent the joint without prohibiting annular motion. ### Claim 7 (depends on 1) The prosthetic device of claim 1, wherein the at least one wire is configured to annularly traverse the joint in a first direction before annularly traversing the joint in a second direction. ### Claim 8 (depends on 1) The prosthetic device of claim 1, further comprising a wire path disposed within the joint. ### Claim 9 A prosthetic device comprising: a finger structure; a flexure cut disposed within the finger structure configured to provide at least one degree of freedom to the finger structure, the flexure cut extending from a surface of the finger structure towards an inner part of the finger structure, the flexure cut traversing through the finger structure in a curvilinear manner; and a sensor disposed within the flexure cut, the sensor configured to measure movement in accordance with the at least one degree of freedom. ### Claim 10 (depends on 9) The prosthetic device of claim 9, wherein the finger structure comprising an outer surface, a first dissected surface and a second dissected surface that define the sides of the flexure cut, wherein the sides of the flexure cut extend linearly inward from an outer surface of the finger structure. ### Claim 11 (depends on 9) The prosthetic device of claim 9, further comprising a proximal portion; a distal portion; a processor disposed in the proximal portion; a joint configured for annular motion, the sensor disposed within the distal portion, and at least one wire connecting the sensor in the distal portion to the processor in the proximal portion, wherein the at least one wire is configured to circumvent the joint without prohibiting annular motion.
