Compared to non-amputees, above knee amputees expend significantly more metabolic energy. This is a result of the passive nature of most knee prostheses, as the development of clinically successful powered knee prostheses has remained a challenge. The addition of powered elements, such as electric motors, allow prosthetic knees to more closely emulate natural knee biomechanics. However, the addition of powered elements presents a new challenge of creating energy efficient devices that do not require frequent charging or excessively large batteries. In this thesis, a general optimization routine was developed to simulate and evaluate the electrical economy of various actuator architectures. Advanced actuators utilizing variable transmissions with elastic elements were compared to direct drive actuators, series elastic actuators, and two novel mechanisms known as the continuously-variable series-elastic actuator (CV-SEA) and the clutchable series-elastic actuator (CSEA). The CV-SEA is similar to a traditional series-elastic actuator (SEA), but uses a controllable continuously-variable transmission (CVT) in between the series-elastic element and the motor. The CSEA included a low-power clutch in parallel with an electric motor within a traditional series-elastic actuator. The stiffness of the series elasticity was tuned to match the elastically conservative region of the knees torque-angle relationship during early stance phase knee flexion and extension. During this region of the gait cycle, the clutch was engaged and elastic energy was stored in the spring, thereby providing the reactionary torque at a substantially reduced electrical cost. The optimization routine showed that the electrical economy of knee prostheses can be greatly improved by implementing variable transmissions in series with elastic elements. The optimization routine also estimated that a CSEA knee prosthesis could provide an 83% reduction in electrical cost, when compared to an SEA knee prosthesis. Although the variable transmission actuators were predicted to be more electrically economical than the CSEA knee, their design complexity limits their current feasibility in a knee prosthesis. Thus, a fully autonomous knee prosthesis utilizing the CSEA was designed, developed and tested. The CSEA Knee was actuated with a brushless electric motor; ballscrew transmission and cable drive as well as commercial electrical components. The knee was lighter than the 8th percentile and shorter than the 1st percentile male shank segment. The CSEA Knee was tested in a unilateral above knee amputee walking at 1.3 m/s. During walking, the CSEA Knee provided biomechanically-accurate torque-angle behavior, agreeing within 17% of the net work and 73% of the stance flexion angle produced by the biological knee during locomotion. Additionally, the process of locomotion reduced the net electrical energy consumed of the CSEA Knee. The knees motor generated 1.8 J/stride, while the electronics consumed 5.4 J/Stride. Thus the net energy consumption was 3.6 J/stride, an order of magnitude less electrical energy consumption than previously published powered knee prostheses. Future work will focus on a custom, power-optimized embedded system and the expansion of the CSEA architecture to other biomechanically relevant joints for bionic prosthesis development.

The amputee patients accompany with muscle power insufficient and proprioception losing because their knee joint construction and major muscle fascicle which control knee flexion or extension were cut. Therefore, amputee patients need to swing their stump to make knee joint flexion or extension. These repeated motions could not swing to target knee angle stably and precisely. In this study, in order to breakthrough these drawbacks, a prosthesis system with power assisted, mechanism design, proprioception compensation was developed and verified. There were static functional verification and dynamic functional verification in this study. In the static functional verification, the linear ruler was used to measure the stroke of actuator developed in this study. Besides, the digital level meter was used to assess the angle control verification. These measured results were compared with targeted values. The mean error of stroke was 0.023±0.175mm, and the mean error of angle was 0.005±0.074°. In the dynamic functional verification, the proprioception compensation and coordinate control modules were considered in the level walking experiments, the differences between affected side and unaffected side were used to evaluate the coordinate control efficiency. The mean maximum flexion angle error was 0.748±0.898° and the percentage error was 1.968%. In addition, the mean delay time was 0.025±0.022 seconds. The experimental results showed that the amputee system developed in this study could provide coordinate level walking for amputee.
