Cambridge Silicon Radio (CSR) has developed a wireless touch surface for computers and mobile devices that has the same thickness as an average sheet of paper.

CSR claims that its latest device is the world’s thinnest wireless touch interface, coming in at just under half a millimetre thick.

The company says the Bluetooth-enabled touch surface combines low power wireless technology with the latest in printable, flexible electronics and touch screen sensing. 

It says that the device could be used as a tablet keyboard cover, similar to that seen on the Microsoft Surface, or used to create large touch zones for a desktop computer.  

Paul Williamson, CSR's director of low power wireless products, said consumers want innovative, portable wireless accessories that work with their mobile devices.

“The ultra-thin touch surface we’ve developed is a perfect example of how Bluetooth Smart can give them just that,” he said. “We’re committed to working collaboratively with developers using the CSR µEnergy platform to help them bring similar next-generation accessories to the market quickly.”

The touch surface is able to connect to iOS 7 mobile devices and Windows 8 PCs and delivers latency speeds of less than 12ms. 

CSR said it collaborated with Atmel and Conductive Inkjet Technology (CIT) to create the wireless touch surface.

Specifically, the device uses Atmel’s touch silicon to sense multiple contact points on a surface, and can offer a full touch surface or power optimised key detection. Meanwhile, the flexible membrane is enabled by CIT printed conductors. 

CSR’s wireless touch surface will be officially unveiled at the IFA consumer electronics trade show in Berlin this week.
