"The wearable, made from flexible, paper-thin latex, is embedded with tiny nodes that push into the skin in a precise way and can move up to 800 times per second. Past devices had low resolution-the touch equivalent of a pixelated image or an early movie from the 1890s with so few frames that the movement looks jerky. Using nodes and arranging them in a particular density improves that resolution."
"The ultrathin new technology, which weighs less than a gram, is designed to be comfortable to wear. "A big goal was to make it very lightweight so you aren't distracted by it," Tan says. "And [to make] something that we call 'haptically transparent'-that means that even when you're wearing it, you can still perceive the real world, so you can perform everyday tasks.""
Researchers at Northwestern University developed a paper-thin latex wearable that fits on a fingertip and renders digital textures such as denim or mesh. The device contains tiny actuating nodes that press into skin with precise timing and can move up to 800 times per second, providing human-level tactile resolution by increasing node density. The ultrathin design weighs less than a gram and aims to be comfortable and haptically transparent so users can still perceive the real world. Users achieved 81% accuracy identifying fabrics like corduroy and leather. Potential uses include online product tactile previews and accessibility tools such as tactile maps or screen-to-Braille translation.
