According to co-author Daniel Xu of this research, “This keyboard is a thin sheet of a special rubber (dielectric elastomer).”
The keyboard is made up of two sensing layers oriented at a 90-degree angle with a single-layered structure. It is able to quickly take advantage of mechanical coupling system from electrical separation.
The surface of this sensor keyboard is divided into 9 different sensing areas.
Researchers have used this rubber in video games to test its functionality, and as a separate project have created a sensing glove that will be used in shooting games in the future.
Several wearables are being manufactured using the Sense Stretching technology in a company called ‘StretchSense’.
The study is published in the journal Smart Materials and Structures.
