Rei Furukawa and her colleagues are conducting research on plastic optical fibers. "We fabricate our own fibers, for example using unique monomer compositions, by adding dopants, dyes, fluorophores, nano-crystals, for example," explains Furukawa. "We are investing new possibilities of plastic-based optical fibers.
Research Highlights
Stretchable electric pumps for next-generation soft robotics
http://www.ru.uec.ac.jp/e-bulletin/research-highlights/2019/stretchable-electric-pumps-for-next-generation-soft-robotics.html
Soft robots that are composed of compliant materials, offer important advantages over conventional rigid robots, such as simplified body structure and control as well as high robustness and versatility.

Inspecting dust on surfaces in product manufacturing: Effect of dirt on inspection surfaces on the accuracy of visual inspection
http://www.ru.uec.ac.jp/e-bulletin/research-highlights/2019/inspecting-dust-on-surfaces-in-product-manufacturing.html
To supply high-quality products to the market, visual inspection by human senses is conducted in many manufacturing industries. It is generally recommended that visual inspection for a high-quality product be performed in a clean room.

Polymer-based optical fiber for visualization of stress
http://www.ru.uec.ac.jp/e-bulletin/research-highlights/2019/polymer-based-optical-fiber-for-visualization-of-stress.html
Fiber-optic strain sensing is known for its ability to monitor large areas. However, most types of fiber-optic strain sensors require spectrum analysis instruments, which drastically increases the overall cost of sensor systems. In contrast, fiber-optic strain sensors such as Bragg-grating or Brillouin optical time domain reflectometers, have reliable structures that are commercially available. However, they are not widely used to support workers in high-risk construction sites.

About the University of Electro-Communications
http://www.uec.ac.jp/
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.
