A new device that could allow people to conduct silent phone conversations has been presented by researchers.
The technology, on display at the Cebit electronics fair in Germany, uses nine electrodes that are stuck to a user's face. It measures the tiny electrical signals produced by muscles used when someone speaks.
The device can record these pulses even when a person does not audibly utter a word and use them to produce synthesised speech in another handset.
"I was taking the train and the person sitting next to me was constantly chatting and I thought 'I need to change this'," Professor Tanja Shultz of the Karlsruhe Institute of Technology told BBC News.
She added that in the future the technology could be loaded into a mobile phone for instantaneous communication.
In other news, identity theft from mobile phones jumped by 70 per cent last year, new figures from the Home Office have revealed.
"New technology creates new opportunities for the user [but] also provides criminals with opportunities," said Home Office minister Alan Campbell.
