Graphene microphone innovation and micro fabrication process

该项目是开发由石墨烯制成的麦克风，用于手机、便携式媒体播放器、笔记本电脑、免提系统、物联网设备等消费电子应用。随着互联网连接的电子环境的出现，许多设备都要求有多个麦克风，从而提供诸如“始终在线”和降噪等功能。这些发展需要低功耗、高灵敏度和经济实惠的小型麦克风设备。语音捕获和识别是另一项需要高质量硬件的功能。石墨烯具有许多理想的性质，如高强度、高柔韧性和高导电性。以前的研究表明，在麦克风中使用石墨烯可以使性能深入到频谱的超声波部分，在改进制造工艺和降低制造成本的同时，实现麦克风的灵敏度和质量。

The project is the development of microphones made from graphene for consumer electronics applications such as mobile phones, portable media players, laptops, hands free systems, IoT devices and many more. With the emergence of an internet connected electronic environment, many devices have requirements for multiple microphones, providing features such as “always on” and noise reduction. These developments require low power, high sensitivity and affordable small form-factor microphone devices. Voice capture and recognition is another feature that requires high quality hardware. Graphene has a number of desirable properties such as high strength, high flexibility and high conductivity. Previous research has indicated that using graphene in microphones can result in performance reaching far into the ultrasonic part of the spectrum, achieving microphone sensitivity and quality while improving the manufacturing process and lowering the cost of manufacture.
