Stretchable Touch Pad Could Become Wearable Touch Screen

Touch pads and touch screens are on nearly every smart device these days. But they can’t go on anything flexible, such as the human body. Scientists have explored stretchable touch panels based on carbon nanotubes, metal nanowires, and other advanced materials, but the performance of these stretchable touch panels fell off sharply when they were stretched. Just as bad, they also fell apart over time when repeatedly stretched. To overcome these problems, scientists at Seoul National University created a touch pad made of the same kind of soft and very stretchable hydrogel used to make soft contact lenses.
