New flexible sensor holds potential for foldable touch screens
Picture a tablet that you can fold into the size of a phone and put away in your pocket, or an artificial skin that can sense your body’s movements and vital signs. A new, inexpensive sensor developed at the University of British Columbia could help make advanced devices like these a reality.
The sensor uses a highly conductive gel sandwiched between layers of silicone that can detect different types of touch, including swiping and tapping, even when it is stretched, folded or bent. This feature makes it suited for foldable devices of the future.
