American Scientists Create Tactile Patch That Lets Users Feel Virtual Objects Through a Screen

Engineers at Northwestern University have developed an ultralight, flexible device called VoxeLite — a thin patch that attaches to the fingertip and can convey sensations of texture, relief, and shape when interacting with a touchscreen.

The patch consists of an elastic film embedded with a grid of microscopic tactile “pixels.” Each element can adjust friction and pressure on the skin, creating the sensation of smoothness, roughness, or three-dimensional forms. In tests, volunteers were able to recognize virtual textures blindly with up to 87% accuracy — a result almost comparable to touching real objects.

The developers believe the technology opens new possibilities for virtual and augmented reality, making interactions more natural and “lifelike.” In addition, the patch could be a useful tool for people with low vision, allowing them to perceive information through tactile signals. Scientists continue to refine the device and plan to expand its functionality, including support for multiple fingers and wireless connectivity.
