Even more function in less and less space - this is the challenge faced by different industries. memetis enables space-saving and powerful microactors 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. Shape memory alloys are thus metallic alloys that can easily be deformed in the cold state, for example by pressure. However, as soon as they are heated, for example by a current pulse, they return to their 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.
