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.
Specific advantages of memetis 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
Implementation of customer-specific applications
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.
- Flat design and reduced dimensions
- Large forces and displacement
- Flexible actuator designs for complex motion
- Silent actuation
- Long lifetime
