In a leap forward for haptic technology, engineers at Northwestern University have developed a groundbreaking wearable device that goes far beyond simple vibrations to deliver rich, multidirectional tactile sensations. Published in Science, their study, “Full freedom-of-motion actuators as advanced haptic interfaces,” introduces a compact, wireless actuator capable of simulating the nuanced feeling of touch—including pressure, vibration, stretching, sliding, and twisting—with remarkable precision.
Unlike current haptic devices that offer basic buzzing or poking feedback, this new actuator moves skin in any direction, creating fully programmable sensations. “Almost all haptic actuators really just poke at the skin,” said John A. Rogers, lead designer of the device. “But skin is receptive to much more sophisticated senses of touch. We wanted to create a device that could push, twist, and slide—not just poke.”
