Transparent thin film acoustic transducers that can effectively work as both acoustic actuators (speakers) and sensors (microphones) are developed in this study. The developed transducer consists of a piezoelectric poly(vinylidene fluoride) (PVDF) thin film coated with compliant carbon nanotube (CNT) based transparent conductors, which are fabricated by CNT acid treatment and layer-by-layer nanoassembly based surface modification of the PVDF substrates. The developed thin film transducers show excellent acoustic response over a broadband frequency range, and have the advantages of being transparent, flexible, extremely thin, and lightweight. The developed transducers could make a significant impact on room acoustics by enabling windows, computer screens, touch panels and posters themselves to server as invisible speakers and microphones.
