24_15/2012Ultrathin Nanosheets: Giant Moisture Responsiveness of VS2 Ultrathin Nanosheets for Novel Touchless Positioning Interface (Adv. Mater. 15/2012)

C. Wu, Y. Xie, and co-workers have created ultrathin nanosheets which act as novel interfaces by sensing the 2D position information of fingertips approaching their surfaces, without any need for physical contact. On page 1969, they describe how these nanosheets are highly moisture-sensitive and respond very quickly, giving both the position and the relative height of approaching fingertips in real time. Such a touch-free interface could enable advanced, highly flexible interactive systems.
