我们展示了灵活的，可折叠的，和透明的声音发射设备（SED）使用银纳米线（AgNW）。采用干法转移技术在衬底上制备了大面积AgNW薄膜。从银纳米线的声发射被测量为功率，距离和频率的函数。在15和45 kHz之间出现显著的平坦和宽的频率响应。声压与理论结果吻合较好。这表明AgNW中存在热声效应。AgNWs-SEDs可以与液晶显示器集成，这显示了成为柔性电子系统中重要部件的潜力。
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.
