A group of researchers led by a South Korean scientist has developed the world’s first meta-learning electro-skin technology that allows typing without a keyboard, the Ministry of Science, Technology and Information and Communication said Wednesday.
The research team of Jo Seong-ho, a computing professor at the Korea Advanced Institute of Science and Technology, Ko Seung-hwan, a mechanical engineering professor at Seoul National University, and Jeenan Bao, a chemical engineering professor at Stanford University, have developed a “new scheme” spray On Smart Skin”.
Researchers sprayed an electrically sensitive liquid onto the skin to automatically print an electrically sensitive nanometer-thick mesh that stretched from the forearm to the back of the hand. The mesh generated electrical signals that caused the mesh to stretch and contract with the movement of the hand. Electrical signals were received by a Bluetooth module attached to the edge of the mesh on the forearm. The collected information was transmitted wirelessly to a computer.
Next, the researchers train the computer’s artificial intelligence to learn different hand movements. They eventually confirmed that they could do different things in virtual space after trying out certain moves a few times.
For example, researchers learned that a spray-on smart skin could learn how your hands and fingers move when you use a keyboard to type certain words, and then use just your hand movements without using a keyboard. was successfully entered into the computer.
According to the researchers, the new scheme could also draw objects on the screen simply by touching them with a hand holding a spray-on smart skin.

The Ministry of Science and Technology pointed out that most existing devices equipped with galvanic skin technology are bulky and lack flexibility, and their structures have limitations in addressing the problems of many joints in the human body.
Researchers say current wearable devices face challenges in expanding into different areas because they rely on mass-collected data with adversity to address different users and purposes. Added.
The ministry emphasized that the study overcomes the limitation of collecting large amounts of data for each movement and has increased the versatility of future wearable devices by allowing electrical sensors to be sprayed directly onto the skin.
“This research is the first case of combining electric skin technology with state-of-the-art artificial intelligence. to the metaverse, augmented and virtual reality, telemedicine, and robotics.”
The research is published in Nature Electronics, a monthly online peer-reviewed journal.
