Touch screens of the future may fold thanks to new sensor

Imagine owning a smartphone or TV that could roll up to fit in your pocket. That could soon be reality thanks a new flexible sensor that can detect subtle differences in touch, including swiping and tapping. Researchers said their stretchable sensor could be used to build folding TV screens and tablets - and may even be used to make skin for robots. The team from the University of British Columbia in Vancouver used a highly conductive gel sandwiched between layers of silicone to make their bendable sensor. To create the sensor, a gel is poured out and combined with silicon-based materials that are stretchy and transparent.
