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 Materials.

"We wanted to show that graphene, although a relatively new material, has potential for real world applications" explains Marko Spasenovic, an author of the paper. "Given its light weight, high mechanical strength and flexibility, graphene just begs to be used as an acoustic membrane material."
