Even more function in less and less space - this is the challenge faced by different industries. memetis enables space-saving and powerful microactuators by using specifically structured thin films of shape memory alloy (SMA). A shape memory alloy (SMA) is also known as a smart material or memory metal. This is due to their ability to "remember" their original shape. Actuators are components that perform a movement or action in the smallest of spaces. memetis thin-film actuators exist at unequal temperatures in two different crystal structures and "remember" an earlier shape even after strong deformation. A shape memory alloy is thus a metallic alloy that can easily be deformed in the cold state, for example by pressure. However, as soon as it is heated, for example by a current pulse, it returns to its original state, to their "shape memory" - the so-called shape memory effect. The forces involved can be used to control the movements of very small components. memetis GmbH uses this behaviour for its work.
