We demonstrated flexible, ultrathin, and transparent sound-emitting devices (SEDs) using silver nanowires (AgNWs). Large area of AgNWs film on substrate was made by dry transfer technique. The sound emission from the AgNWs was measured as a function of power, distance, and frequency. Significant flat and wide frequency responses occurred between 15 and 45 kHz. The sound pressure was in good agreement with theoretical results. This indicates that a thermoacoustic effect exists in AgNWs. The AgNWs-SEDs can be integrated with the liquid crystal display, which shows the potential to be an important component in flexible electronic systems. (C) 2011 American Institute of Physics.
