Graphene microphone outperforms traditional nickel and offers ultrasonic reach

Posted by in category: materials

Scientists have developed a graphene based microphone nearly 32 times more sensitive than microphones of standard nickel-based construction.

The researchers, based at the University of Belgrade, Serbia, created a vibrating — the part of a condenser which converts the sound to a current — from graphene, and were able to show up to 15 dB higher sensitivity compared to a commercial , at frequencies up to 11 kHz.

The results are published today, 27th November 2015, in the journal 2D Mater ials.
