Transmission accuracy reaches 97%

Today there are already devices that allow people to send and receive tactile sensations, but they are often quite cumbersome. The new development of scientists from the South Korean Research Institute of Electronics and Telecommunications (ETRI) is significantly smaller and can be placed on the arm.

The current prototype is a compact board with a thin and long piezoelectric element less than 1 mm thick. Such an element generates a small current if the user swipes a finger across a textured surface. The signal is then transmitted over a radio channel to another user.

On the other hand, if you apply electricity to the piezoelectric element, it will vibrate. This allows you to transmit such sensations literally in real time. The delay is only 1.55 ms at a distance of up to 15 meters.

The system was able to transmit tactile sensations from materials such as cotton, polyester, spandex, raised lettering, and so on with an accuracy of 97%. In the future, it is possible that the technology will also allow the sensations of hot and cold surfaces to be transmitted. it is also planned to improve the transmission accuracy.

As a result, this will allow the creation of technologies for a very deep virtual immersion, however, no specific dates have yet been announced.
