Actuators for the Automotive Industry and Mobile Units

In cooperation with Actuator Solutions, DIS has developed actuators for the automotive industry and mobile units. Actuator Solutions GmbH is the world’s largest manufacturer of Shape Memory Alloy (SMA) actuators for the automotive industry, mobile units, and the pharmaceutical industry. It is also a joint venture between two market-leading companies, both pioneers within their respective industries: SAES GETTERS, which produces and supplies SMA-wires, springs, and components, and Präzision SE, which produces innovative precision systems for the pharmaceutical and automotive industry.

SMA belongs to a group of high-tech and super-elastic materials that can be formed into predefined shapes when heated. Actuator Solutions utilizes the special features of SMA to develop innovative, compact, energy-saving, and low-noise lightweight actuators for products such as microfluidic and micro-optical drives for all relevant industries.


Actuator Solutions and DIS have collaborated since 2012, and DIS has played a role in the development of several different actuators for the automotive industry and mobile units. One of the projects in which DIS has participated involves the mechanical design and development of a valve used for a massage function in luxury car seats. This massage function is controlled by numerous small valves in the seat backrest. These regulate the cyclic ventilation in the pneumatic lifting elements in a pattern, ensuring that the driver experiences the highest possible comfort while driving. Given that the massage function in the car seat requires many valves, using compact and lightweight SMA valves offers an advantage over conventional valves.


We have worked with DIS for several years and the advantage for us is that we have a partner who knows the SMA technology, and who knows how we at Actuator Solutions wish to implement it in our products, so that we can keep our leading position in the market for SMAactuators, says Markus Köpfer, CEO at Actuator Solutions GmbH.
