There’s been growing demand for new growth engines, along with the commercialization of the 5G network and the arrival of the era of hyperconnectivity. And a new communication technology that can overcome the limitations of the existing communication networks and use the human body tissue as the transmission medium, has been developed. It is human body communication, or HBC technology, which can enhance the transfer performances of wearable devices or biosensors by providing stable transmission of information. Electronics and Telecommunications Research Institute has continuously carried out researches to commercialize human body communication technologies. And System on Chip, which is a controller developed for human body communication, is one of the examples. The research team has developed a capsule endoscopy which can diagnose throat and stomach more effectively by implementing a human body communication technology. Thanks to the high-speed data transfer which can send 24 pictures per second, it is possible to closely watch the parts like throat which passes through rapidly. Human body communication technology can also be used for the care of parents who live far apart or the elderly who live alone. By using the touch tag, various behaviors of people can be analyzed and the data can be transmitted to people who are far away. And a patch-type sensor, which can measure biosignals including body temperature, humidity and movements of body for 24 hours a day, has been developed. The data can be collected only by attaching the sensor to the skin, just like attaching a bandaid. We introduce human body communication technology, which uses human body tissues for the intuitive communication among users.
Electronic skin is an electronic device that can sense temperature, humidity and pressure, just like human skin. As it can be applied to a wide range of areas including flexible display, wearable device and robot for surgical operations, a lot of efforts have been made to develop and commercialize the device. And a domestic research team has developed a 3D tactile sensor array which enables direct measurement and expression of touching sensation. 3D tactile sensor array has more than 100 times stronger degree of precision in comparison to existing recognition equipment. When developing electronic skin and applying it to a robot, monitoring of heart rate and blood pressure as well as production of data on human body based on the AI technology can be realized. A domestic research team has developed a transparent electrode which can be stretched according to different body parts, by implementing the principles of kirigami. And it has been applied to electronic skin. Transparent electronic skin can be attached to different body parts with rough surface. And it can recognize bio-signals including electromyogram and body temperature. And a self-healing semiconductor sensor, which can be stretched and heal itself just like human skin, has been developed. The sensor has been considered as “super skin” as it responds more sensitively to external stimulus than human skin. Electronic skin has imitated the functions of human skin and it has evolved continuously based on the sophisticated technologies. We look into electronic skin, which will bring innovation to the future robot industry, as well as the medical and electronic equipment sectors.
Coding is a process of creating computer programs by using a programming language. As coding has become a compulsory subject for students, coding education has grown in significance. And a variety of educational methods, which make use of robots and drones to help students understand the concept of coding, have been developed. Robot is a tool that has been actively used for the development of friendly coding education. Students can learn the basic principles and concepts of coding naturally by creating effective movements of a robot. The educational drone market, which enables coding education with drones, has recently been in the spotlight. It is possible to control drones only with coding, without additional controlling equipment. And it has gained a lot of popularity as people can learn about drone and coding at the same time. Also, it is possible to make a lot of drones fly at the same time. Moreover, a method that enables students learn coding at outdoor spaces has been developed. We report on the coding education market where a variety of educational methods that can arouse interest of students and help them learn creative thinking skills have been developed.
