Psychosensory Electronic Skin Technology for Future AI and Humanoid Development

DGIST has announced that Professor Jae Eun Jang's team in the Department of Information and Communication Engineering developed electronic skin technology that can detect "prick" and "hot" pain sensations like humans. This research result is expected to be applied on the development of humanoid robots and patients wearing prosthetic hands in the future.

The attempt to mimic human's five senses led to the development of innovative electronic devices such as camera and TV, which are inventions that dramatically changed human life. As a result, many scientists are continuously performing research to imitate tactile, olfactory, and palate senses and tactile sensing is expected to be the next mimetic technology for various reasons.

For this, the research team focused on zinc oxide nano-wire (ZnO Nano-wire) technology, which was applied as a self-power tactile sensor that does not need a battery thanks to its piezoelectric effect, which generates electrical signals by detecting pressure.

Professor Jang in the Department of Information and Communication Engineering said "We have developed a core base technology that can effectively detect pain, which is necessary for developing future-type tactile sensor. As an achievement of convergence research by experts in nano engineering, electronic engineering, robotics engineering, and brain sciences, it will be widely applied on electronic skin that feels various senses as well as new human-machine interactions.
