A paper-thin wireless touch surface with Atmel

Cambridge Silicon Radio (CSR) has developed an uber-thin wireless touch interface. The flexible interface, measuring less than 0.5 mm thick, turns any area into a touch surface for mobile devices and even desktops.

“Lightweight and flexible, the device can be integrated into a protective cover or used to create large touch zones on a desktop,” a CSR rep explained. “With minimal weight and bulk, a full keyboard experience can be added to a tablet without taking up valuable screen area. Thin enough to slip behind the pages of a notebook, it can be used to pick up handwriting and sketches from the nib of a modified pen.”

So how does it work? Well, the paper-thin surface is wirelessly connected using the CSR1010 chip which is optimized for Bluetooth smart, allowing it to link to the latest iOS7 mobile devices and Windows 8 PCs. Meanwhile, touch latency is minimized to less than 12mS, ensuring near instant visual feedback and enabling a seamless user experience.

To create the ultra-thin wireless touch surface, CSR partnered with Atmel and Conductive Inkjet Technology (CIT). More specifically, the device uses Atmel’s touch silicon tech to sense multiple contact points on a surface – and is therefore capable of offering a full touch surface or power optimized key detection.

CSR will be showcasing its ultra-thin touch surface at IFA Berlin (Hall 1.2 Stand 104) from September 6-11, 2013.
