World's 'smartest face-mask' presented

Gaming company Razer has made what they claim is world's smartest face mask - complete with a built-in microphone.

The prototype, revealed at the tech convention CES, claims to amplify the users' voice - to prevent muffled speech, BBC News reports.

The design includes active ventilation - exhaling warmer exhaled air whilst pulling in cooler air.

The company says the mask is classified as an N95 surgical mask, however the BBC has not reviewed the product.

The mask itself is made of transparent plastic, making it easier for people to lip read and pick up on facial cues.

A transparent mask is hardly an innovation itself - there are plenty on the market. However the company says the mask also has a "low light mode".

That means the mask's interior lights up automatically when dark - illuminating your mouth. Razer claims this allows you to "express yourself clearly regardless of the lighting conditions".
