Smart films can now be used as a new type of speaker driver, replacing the electromagnets or permanent magnets that drive the loudspeaker membranes in conventional speaker systems. But the film can also be made to generate acoustic tones – essentially turning it into its own loudspeaker. Sophie Nalbach conducted research into these smart polymer films as part of her doctoral thesis in Professor Stefan Seelecke's group.
