Recent developments in nano/micro technology have made it possible to construct small-scale sensing chips for the analysis of biological markers such as nucleic acids, proteins, small molecules, and cells. Although biochip technology for the diagnosis of severe physiological diseases (e.g., cancer, diabetes, and cardiovascular disease) has been extensively studied, biochips for the monitoring of human emotions such as stress, fear, depression, and sorrow have not yet been introduced, and the development of such a biochip is in its infancy. In this session we discuss the potential importance of biochip technology in which human emotion can be precisely measured in real time using body fluids such as blood, saliva, urine, or sweat. We call these biochips emotion-on-a-chip (EOC). These techniques provide new opportunities to precisely investigate human emotion. Future developments in EOC techniques will combine social and natural sciences to expand their scope of study.


Hyo-Il Jung received the B.Sc. and M.Sc. (Biotechnology) degrees from the Korea Advanced Institute of Science and Technology (KAIST), South Korea in 1993 and 1995, respectively, and the Ph.D. (Physical Biochemistry) degree from the University of Cambridge, United Kingdom. He is currently a professor at the School of Mechanical Engineering, Yonsei University, and his research interests center on microfluidic biosensors, cancer diagnosis, and affective engineering.
