Multiple Sensor Fusion Technology for Non-contact Measurement of Vital Signs and its Clinical Applications
There is increasing interest in technology for non-contact measurement of human vital signs (heart rate, respiration, and body temperature), which are important for understanding the state of a person's health. New biological measurement sensors have been developed as well as reports on methods for measuring respiration or heartbeat using pressure sensors, microwave radar, RGB camera, and thermography. This technology has wide-ranging applications. Guanghao Sun's group is developing clinical applications for monitoring elderly people, identification of sleep apnea, detection of patients who may carry infectious diseases, and noncontact measurement of stress levels [1-2].

Frontiers of state of the art precision molecular spectroscopy
The mid-infrared wavelength region is attractive and important for fundamental physics as well as applications such as atmosphere chemistry due to the existence of so-called "molecular fingerprints" that are inherent and strong absorption lines for individual molecules. The detailed analysis of fingerprints reveals the internal structure of molecules and verifies fundamental theories of physics. In the mid-infrared region, especially longer than wavelength of 5 μm, however, the availability of suitable light sources for precise spectroscopy, that is laser source having high power and high frequency stability, are extremely limited. In addition, it is technically challenging to do sensitive spectroscopy in the mid-infrared region because of large noise and small dynamic range of photo detectors.

Technology for processing wood powder with natural additives
Biomass materials such as wood are environmentally-friendly alternatives to fossil resources. As an example, wood is typically non-toxic and carbon neutral. Furthermore, wood can be produced in a sustainable manner by appropriate planting and trimming of trees. Therefore, the use of wood resources as industrial materials is an important aspect for realizing a sustainable society.

Technology for processing wood powder with natural additives
Shohei Kajikawa
Shohei Kajikawa working on new processing methods for metals, wood, etc., and the optimization of methods for conventional processing methods.
The specific target of his research is materials processing technology, such as plastic forming, that is used to manufacture parts for all kinds of products ranging from automobiles, home appliances, furniture, housing materials, stationery, etc., that we use daily. If such parts can be manufactured easily and in a short time, it is possible to reduce the cost of products around us as well as reducing the burden on our environmental by improving processing efficiency.

About the University of Electro-Communications
The University of Electro-Communications (UEC) in Tokyo is a small, luminous university at the forefront of pure and applied sciences, engineering, and technology research. Its roots go back to the Technical Institute for Wireless Commutations, which was established in 1918 by the Wireless Association to train so-called wireless engineers in maritime communications in response to the Titanic disaster in 1912. In 1949, the UEC was established as a national university by the Japanese Ministry of Education and moved in 1957 from Meguro to its current Chofu campus Tokyo.
With approximately 4,000 students and 350 faculty members, UEC is regarded as a small university, but with expertise in wireless communications, laser science, robotics, informatics, and material science, to name just a few areas of research.
The UEC was selected for the Ministry of Education, Culture, Sports, Science and Technology (MEXT) Program for Promoting the Enhancement of Research Universities as a result of its strengths in three main areas: optics and photonics research, where we are number one for the number of joint publications with foreign researchers; wireless communications, which reflects our roots; and materials-based research, particularly on fuel cells.
