When it comes to haptic feedback, most technologies are limited to simple vibrations. But our skin is loaded with tiny sensors that detect pressure, vibration, stretching and more.
Now, Northwestern University engineers have unveiled a new technology that creates precise movements to mimic these complex sensations.
The study will be published on March 28 in the journal Science.
While sitting on the skin, the compact, lightweight, wireless device applies force in any direction to generate a variety of sensations, including vibrations, stretching, pressure, sliding and twisting. The device also can combine sensations and operate fast or slow to simulate a more nuanced, realistic sense of touch.
Powered by a small rechargeable battery, the device uses…
