Ultra-High Sensitivity Fiber Optic Microphone with Corrugated Graphene Diaphragm for Voice Recognition
1Introduction To avoid the interference of unexpected background noise and obtain high-fidelity voice signals, voice recognition urgently requires acoustic sensors with high sensitivity, flat frequency response, and high signal-to-noise ratio (SNR). Graphene oxide (GO) has gained widespread attention due to its controllable thickness and high tensile strength. However, low mechanical sensitivity (SM) caused by undesirable … Read more
