A new ultra-thin wearable device - as thin as a temporary tattoo - is capable of replicating the sense of being touched, remotely. The groundbreaking technology has been developed at the Centre for Materials Interfaces of the Italian Institute of Technology (IIT) in Pontedera, Italy. The electronic tattoo, designed by IIT researchers Arianna Mazzotta and Virgilio Mattoli, is a few micrometers thick and generates a tactile sensation. Creating a force that pushes against the wearer's skin. Researchers are actively working on implementing displays featuring multiple tactile pixels, known as taxels. These taxels can be independently activated, enabling the reproduction of letters, numbers, and dynamic patterns on the skin. You could even keep in touch with loved ones, literally! Resembling a temporary tattoo, the device is small, easy to wear, and applies a highly localised force, restoring tactile sensation to the skin it adheres to. Preliminary usage tests have shown promising results, suggesting the potential for this technology to become a new standard in manufacturing lightweight, portable, and energy-efficient tactile displays.
