Datwyler acquisition solidifies electroactive polymers expertise

SCHATTDORF, Switzerland—Datwyler Holding Inc. has strengthened its innovative polymer capabilities with the acquisition of Swiss startup CT Systems S.R.L.

A spin-off of the Swiss Federal Laboratories for Materials Science and Technology (EMPA), the Zurich-based high-tech startup specializes in dielectric elastomer.

The acquisition follows four years of collaboration between the two sides to develop electroactive polymers, Datwyler said, noting the purchase will secure patents for the technology.

The parties agreed not to disclose the terms of the agreement.

With a "unique stacked design," electroactive polymers enable new applications in a number of areas, including future automotive and in general industry, Datwyler said. In particular, the Swiss group expects to use the technology to produce stack actuators on an industrial scale for the first time. The product can replace conventional actuator technologies to offer low energy consumption, fewer mechanical parts, low weight and volume as well as a "robust and durable" design.

Datwyler is working to build a "proprietary, highly automated production line" at its existing plant in Schattdorf for the manufacture of the actuators.

Lab samples are available, and delivery of the first industrial prototypes is planned for early 2024.

According to Datwyler, the stacked electroactive polymers offer a wide range of novel actuator and sensor applications. The actuators can be used to control switches, locks, valves and to operate pumps. Applications include thermal management in electric vehicle batteries, as well as actuation of mechanical components, dashboard vents or valves for pneumatic massage seats.

Electroactive polymers also can realize haptic feedback and morphing surfaces for human-machine interface applications. Examples include haptic feedback on displays and on the steering wheel, or control elements morphing out of a plain surface.

Datwyler is in talks with existing and potential customers and exploring initial development projects.

"With our strengthened expertise in electroactive polymers, we are a leading supplier for smart-rubber applications," said CEO Dirk Lambrecht. "I am convinced that the technology with electroactive polymers has the potential to become one of our high-revenue product lines in the long term."
