Our years long experience in creating extremely thin, light-weight and high power density shape memory alloy (SMA) actuators has helped our customers create smart coupling mechanisms and develop in-space automation instruments like never before.
We are eager to hear what your challenge is!
Our actuators are made from intelligent materials - the so-called shape memory alloys (SMA). These are metallic alloys which after deformation "remember" their original shape and restore it independently when heat is applied.
With this shape memory effect, great forces are released and great distances can be covered.
The fields of application for memetis actuators are diverse.
Let us discuss applications in your industry!
Coupling closed - martensite (low temperature phase)
The actuator (blue) is not heated and is fully deflected by the force of a return spring. The coupling is closed.

Coupling opens - Phase transformation
The actuator is now increasingly heated. The alloy transforms into its memory form and builds up a counterforce to the return spring.

Coupling open - austenite (high temperature phase)
Actuator (red) is now sufficiently heated and realizes sufficient power to fully open the coupling. A smooth coupling is now possible.

The long-established German company Gebr. Märklin & Cie. GmbH is known worldwide for its model railways and is market leader in the European model railway industry. memetis supports this with its ultra-compact linear actuators for "even more authentic movement in the smallest space".
As the European market leader in the model railway industry, Märklin also pursues the goal of innovation leadership in relevant markets. The aim is to continuously increase the functionality of the detailed Märklin models while keeping an eye on authenticity. This enables an even better customer experience and a strong positioning in the market.
The attractiveness of the Märklin models can be enhanced by additional physical functions, such as those offered by the new telex coupling. In most cases, only very limited installation space is available, which additionally competes with the complex model electronics or other drives. This requires an actuator solution that allows controllable movement with relatively large travel and forces at minimum dimensions.
memetis manufactures a linear actuator that meets the requirements of Märklin: Large forces and travel ranges with the smallest possible dimensions. In addition, more realistic movement and slim design are guaranteed.
"We build the best model locomotives in large series and convey the prestige of the brand through value - this also means that we [...] shift the boundaries of miniaturization to achieve a higher degree of miniaturization. [...] This category also includes the slimming down of the telex coupling by a miniature actuator."
"Busch-Jaeger constantly meets the highest demands of its customers in terms of quality, product range and innovation. For our smart home products and systems we are therefore always looking for advanced solutions. The memetis team has worked with us to develop technically sound concepts and functional prototypes within a very short time. We are very satisfied with the final result and look forward to further projects with memetis."
"Victorinox focuses on product design and quality and is always looking for ways to increase functionality. For developing a new function on one of our Travel Gear product, we approached memetis for their expertise in miniature actuation. They proved to be a very reliable project partner who acts fast and delivers what they promise. We were very pleased that memetis quickly developed a sophisticated prototype that met our full expectations. This is one of the reasons why we can thoroughly recommend the actuator solutions from memetis."
