In this talk, two of our research activities at NEC Corp. will be presented.
Firstly I will present some of our work about nano- and micro-structured biochips. In this topic, using some movies, I will explain the world's first artificial-gel chromatography units and continuous-flow separation units for DNA analysis, and hydrophilicity-controlled chips with microstructure for proteome analysis. 
Secondly, I will talk about our work in developing proximity presence sensing systems. When the Internet of things will come true, the number of sensor nodes will be said to reach 1 Trillion! What type of sensor nodes can be so massively deployed? 

Many research groups such as the Auto-ID lab at MIT are proposing sensing systems using ordinary passive 10-cent RFID tags as sensor nodes. However, these currently still suffer from unacceptable false detection rates and tend to not be practical due to their far field operation. In this talk, I will describe some of our work in introducing near-field traveling-wave coupled modes to suppress false detection sufficiently to allow for practical use of the technology.
