Product description

They might only be made from thin silicon film, but they can squeeze down hard, deliver a powerful thrust, vibrate or hold any required position. And because they can act as sensors, they are becoming important tools in technical applications. Stefan Seelecke and his team at Saarland University are developing a new generation of polymer film-based engineering components that can be used as continuous switches, self-metering valves, motorless pumps or even as tactile aids for touchscreens. The technology needs neither rare earths nor copper, it is cheap to produce and consumes very little energy and components made using it are astonishingly light. The engineering team from Saarland University is in Hannover to look for industrial partners interested in developing the new technology.

The team will be showcasing the potential of their technology at Hannover Messe from the 23rd to the 27th of April at the Saarland Research and Innovation Stand (Hall 2, Stand B46) where they will be demonstrating how these electroactive films respond when they come into contact with other objects.
