Sensors have already impressively demonstrated the possibilities of miniaturization in recent years. However, we face major challenges when it comes to miniaturizing movement. Previous technologies are reaching their physical limits. memetis is actively addressing these limits.
Intelligent materials - the so-called shape memory alloys (SMA) - are used in our actuators. These are metallic alloys which, after deformation, seem to "remember" their original shape and restore it independently. With this shape memory effect, great forces are released and great distances are covered. We use these properties specifically to manufacture high-performance actuators with unsurpassed working density in a compact format.
In addition to our customer-specific actuator developments, we offer various actuators (movement in the plane, perpendicular to the plane as well as swivel movement) for evaluation. Download the data sheets here to compare the specifications with your application idea.
Continuing major challenges for further miniaturization in limited quantities show the limits of conventional actuator technologies. Various challenges can currently be observed in the field of MEMS (micro-electromechanical systems): Adaptability to new applications, continuous miniaturization and an increased degree of "intelligence" (i.e. complexity, range of functions). These challenges are completely addressed by memetis SMA miniature actuators.
The specific advantages of film-based SMA actuators are a simple, highly adaptable design, a robust operating principle (electrical resistance heating), silent operation and very high working densities compared to other actuator technologies. Shape memory alloys also offer advantages in terms of biocompatibility. By using foils instead of wires, the additional advantages are a large surface-to-volume ratio (short switching times independent of actuator force) and the feasibility of complex structures (combination of several or multi-dimensional actuators in a single component). As a result of current research, fatigue-free materials with significantly increased operating times (> 100 million switching cycles) are now available.
Smart Materials such as SMA allow targeted and intelligent actuators in corresponding systems by means of corresponding control electronics and software.
With memetis actuators, our customers receive a completely new type of actuation for integration into their own product range. This actuation usually brings various advantages, which, however, depend strongly on the context of the intended application. memetis offers its customers an actuation which is characterized by clear strengths.
Nowadays, different types of actuation, i.e. movement through technical components, are to be implemented in a multitude of applications. But the mere implementation of motion does not meet the demands of today's industries. Movement must be realized in the smallest possible space with the greatest possible force and distance. The application possibilities are far from exhausted.
memetis actuators' fields of application are diverse.
The aim is to convey as concrete a picture of the possibilities as possible.
Let us discuss applications in your industry.
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.
