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, “Full freedom-of-motion actuators as advanced haptic interfaces,” is published 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 can also combine sensations and operate fast or slowly to simulate a more nuanced, realistic sense of touch.
