Artificial muscles based on coiled UHMWPE fibers with shape memory effect

Three-Dimensional Hysteresis Modeling of Robotic Artificial Muscles with Application to Shape Memory Alloy Actuators

Being inherently compliant, the robotic artificial muscles are increasingly popular in applications such as safe human-robot interaction, legged robotics, prostheses and orthoses, and soft robotics. Their full utilization is often challenged by the coupled hysteresis among input, strain, and tension force. Although conventional two-dimensional hysteresis models are available, no prior studies o...

Effect of Electrical Current on Nitinol Medical Staples Shape Memory

Medical staples are one of the nitinol shape memory alloys applications which their pedicles have to be bent for suitable function with an appropriate angle at a specified temperature .It is achievable by shape memory effect. For this purpose, samples of nitinol super elastic alloys were bent in a steel mold with different angles & formed orthopedic staples. Then shape memory effect was induced...

Artificial muscles based on conducting polymers

Natural muscles have mechanical properties that conventional actuators do not possess. These natural machines show large strain, moderate stress, high efficiency and stability, fast response time, high power/weight ratio, long lifetime, etc. In the last years a great interest has arisen to develop materials that mimic natural mechanisms. Conducting polymers have an array of potential applicatio...
