BEXCO, the conference venue
The IEEE SENSORS is a flagship conference in the field of sensors and their related fields. It brings together researchers, developers, and practitioners from diverse fields including international scientists and engineers from academia, research institutes, and companies to present and discuss the latest results in the general field of sensors. This year, it was held in Busan, the 2nd largest city of South Korea. There were more than 950 abstract submissions; among them 533 abstracts were accepted (acceptance rate <60% ). 272 were presented in oral and 261 in poster sessions, depending on where the paper best fits into the technical program. Next year, IEEE SENSORS will be held in Orlando, Florida, USA, 3 to 6 November 2016.

In this conference, my contribution was assigned to the Poster session A3P-H "Advanced Materials for Chemical Sensing" in the afternoon of Nov 1st. I presented my research titled "Detection of Individual CO2 Molecules Adsorption with Suspended Graphene in an Electrical Field". I reported here the first ever electrical detection of individual carbon dioxide molecular adsorption using suspended graphene. I designed a novel device architecture to prevent the collapsing of graphene onto substrate with the application of gate voltage by inducing a large strain. Thus, the electrical field can be introduced to graphene surface by applying back-gate voltage in order to control the molecular adsorption rate. In the experiment, the step-like resistance changes of ～ 0.56% were measured in graphene upon the exposure to CO2 molecules as the response to the individual adsorption event. The measurement showed a good agreement with the theoretical results of the first principle calculations, which suggested a change of ～ 0.87% in graphene to a single molecule adsorption event.
I was very grateful to join in this IEEE Sensors Conference, which has served and provided various activities to learn the current researches and to exchange the ideas. In the symposium of biosensor research, I could communicate and discussed ideas with other researchers including some experts in the field. I also received some feedback and questions in my presentation, which are helpful and valuable to sharpen and expand my consideration in next study. In general, my attendance in IEEE Sensors Conference would be a great and meaningful experience for me to broaden the networking in the scientific research community and to stimulate further motivation for future research.
