A keyboard that is as slim as a piece of paper has been described as the world's thinnest by the product's designers who have been showing it off at the IFA 2013 tech fair in Berlin

The BBC's Technology correspondent Rory Cellan-Jones tested the device, which is a mere 0.5mm thick, and spoke to CSR's Paul Williamson about other applications for the technology.
