'Artificial throat' for speech-impaired made using graphene
Chinese researchers have developed an 'artificial throat' using graphene (a carbon form) which can both generate and detect sound. The wearable electronic device can help the deaf-mute 'speak' as it detects weak vibrations when attached to the throat, converting it into sound. The graphene-based biocompatible device is expected to have a significant impact in speech recognition, scientists said.
