Forget traditional comic book hero origin stories — gaining a super sense of touch can be as easy as slipping on this glove.

It works through stochastic resonance, where adding a tiny amount of white noise to an area of the body can heighten senses like sight, hearing, balance control and touch.

But until now, no one has built a wearable device that takes advantage of these superhero-style powers. That’s where Georgia Tech assistant professor Jun Ueda, associate professor Minoru Shinohara and visiting scholar Yuichi Kurita come in.

Their magic glove has a gap at the fingertip so the person wearing it still feels objects with their skin. But an actuator — made of lead zirconate layers stacked one upon the other to generate the kind of high-frequency vibration needed — makes contact with the finger to vibrate it.

The glove was trialled on ten adult volunteers. The tasks included having their finger tips pricked with sharp points, feeling the weight of filament in fiber strands and differentiating between different types of sandpaper through touch alone.

In each task, the researchers saw statistically significant improvements in the volunteers’ sense of touch. Some tasks saw more improvement than others, and each volunteer had a slightly different vibration amplitude threshold — but all of the tests showed that wearing the glove lead to a heightened sensory experience.

“This device may one day be used to assist individuals whose jobs require high-precision manual dexterity or those with medical conditions that reduce their sense of touch,” said Ueda in a press release.
