Graphene microphone innovation and micro fabrication process

该项目是由石墨烯制成的麦克风的开发，用于消费电子应用，如手机、便携式媒体播放器、笔记本电脑、免提系统、物联网设备等。随着互联网连接电子环境的出现，许多设备都需要多个麦克风，提供诸如“始终打开”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尺寸麦克风设备。语音捕捉和识别是另一个需要高质量硬件的功能。石墨烯具有许多理想的特性，如高强度、高柔韧性和高导电性。先前的研究表明，在麦克风中使用石墨烯可以使性能远远达到超声波部分的频谱，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.
