Smart films help to make loudspeakers lighter and more energy-efficient

Professors Stefan Seelecke and Paul Motzki at Saarland University are developing intelligent materials that are opening up new avenues in sound reproduction technology: lightweight loudspeakers that use far less energy than their conventional counterparts, novel shapes for sound and signal generators and applications involving noise canceling textiles. The basis for these smart materials are ultrathin silicone films that can act as artificial muscles with their own built-in sensors. The research team will be showcasing their new technology at this year’s Hannover Messe from 17 to 21 April (Hall 2, Stand B34).
