One of the greatest challenges in the design of shape-memory elements (mostly binary Nickel-Titanium wires) is to ensure that the required travel (stroke) is achieved, as this is subject to variation due to various influencing factors. One way of pre

Actuators based on the shape memory effect have recently become more and more economically important due to the many advantages of shape memory alloys (SMAs), such as their high energy density. SMAs are usually used to control the end/maximum positio

Shape memory alloys (SMA) are often used to drive actuators, whereby SMA have a very specific fatigue behavior, which influences the lifetime of these actuators. The optimization of the actuator’s lifetime is an important topic to make these innova

Integration of shape memory alloys (SMA) into actuator systems is still challenging, since mechanically and electrically anchoring are needed to provide stroke and trigger the shape memory effect (SME) in a controlled manner. A direct connection of S

Predicting the stroke (respectively the strain) of binary Nickel-Titanium (NiTi) shape memory alloy (SMA) wires is a challenging, but interesting task for designers of SMA components. Due to fatigue the resulting stroke decreases with an increasing c

Nickel-Titanium (NiTi) shape memory wires have established themselves in the actuator market (medicine, automotive industry, aerospace) because of their high power density and their simple activation by resistance heating. The actuator stroke, normal

Shape Memory Alloys (SMA) exist in several forms, such as wires, tubes, springs and several more. Most commonly available SMA forms are wires, contracting when heated. There are several ways to activate the effect in wires, but mostly they are electr

The integration of shape memory (SM) wires in additive manufacturing (AM) processes and components, either as actuators or sensors, holds enormous potential for future developments. For example, a sensor or an actuator function could be integrated in

Predicting the remaining lifetime of an operating shape memory actuator is a great goal to achieve to increase its reliability. The shape memory wires used in these actuators are mostly activated using Joule Heating. Therefore the electrical resistan
