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 Styrene Ethylene Butadiene Styrene (SEBS) thin film with compliant carbon nanotube(CNT), Graphene, carbon nano fiber(CNF), carbonblack filler and paraffine oil based transparent conductors, which are fabricated by CNT, Graphene, carbon nano fiber(CNF), carbonblack filler and paraffine oil acid treatment and layer-by-layer nano assembly based surface modification of the SEBS 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. |
