Abstract Transparent thin film acoustic transducers that can effectively work as both acoustic actuators and sensors 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 nano assembly based surface modification of the PVDF substrates. The developed thin film transducers show excellent acoustic response over a broadband frequency range, and have the advantage of being transparentl flexible, extremely thin, and lightweight. The developed transducers could make a significant impact on room acoustic by enabling windows, computer screens, touch panels and posters themselves to server as invisible speakers and microphones. |
