Shape memory alloy (SMA) actuation is becoming an increasingly viable technology for industrial applications as many of the technical issues that have limited its use are being addressed (speed of actuation, mechanical connections, performance degradation, quality control, etc.) while increasing production capacities drive costs to practical levels. Shape memory alloys are often selected becaus...

Shape memory alloys (SMA) show a high ratio of work capacity per material volume. This makes the application of SMA especially useful in micron-sized systems. The development of robotic grippers is one important prerequisite for the successful automation of the assembly of micro systems. Therefore the SMA may also play a role, for example, as actuators in micron-sized grippers. This paper prese...

Position control of Shape Memory Alloy (SMA) actuators has been a challenging topic during the last years due to their nonlinearities in the governing physical equations as well as their hysteresis behaviors. Using the inverse of phenomenological hysteresis model in order to compensate the input–output hysteresis behavior of these actuators shows the effectiveness of this approach. In this pape...

Light-driven shape memory alloy (SMA)-based microscale actuators show great promise for artificial muscle and biomedical applications, as they are actuated remotely have a fast response speed. However, ultraviolet (UV) light is required device actuation; thus, the operating environment has been limited. Here, an infrared (IR) light-driven SMA actuator proposed, in which plasmonic effect used to...

Shape Memory Alloys (SMA) are a group of metallic alloys that can return to their original shape when subjected temperature transformation between two phases. SMAs have been used as an alternative solution conventional actuators in different applications the robotics, biomedical, aerospace and automation domains because characteristics; being one leading solutions fields such soft robotics bio-...

In this paper we present a walking pattern filter for Shape Memory Alloy (SMA) actuated biped robots. SMAs are known for their slow response. The actuation speed limitation can potentially lead to stability problems for biped robots. This filter adapts the human motion for a SMA biped in order to have a stable walking pattern. The Zero Moment Point (ZMP) is used as a main criterion of the filte...

Shape memory alloy (SMA) actuators have recently demonstrated their potential for various applications in fields such as robotics, medicine, aerospace, and automotive. Its features, low weight high force, simplicity, noiseless operation, cost compared with other conventional actuator, are only a few advantages of this which is receiving increasing interest among researchers. However, the use th...

The present paper describes the design of a hybrid actuation control concept, a fuzzy logic proportional-integral-derivative plus a conventional on-off controller, for a new morphing mechanism using smart materials as actuators, which were made from shape memory alloys (SMA). The research work described here was developed for the open loop phase of a morphing wing system, whose primary goal was...
