AboutAbout the lab
Making electronic devices from soft organic materials
The Advanced Electronic Devices Lab (Sekitani Lab) studies soft electronic devices made from organic materials.
The research highly controls the molecular structure, electronic states, and physical properties of organic materials, and develops them into flexible electronics and photonics.
The lab's motto is to learn everything from academic work rooted in basic sciences such as mathematics and physics to systems that contribute to real society.
Students can be involved in a wide range of electronic device manufacturing, from materials synthesis, circuit design, fabrication processes, and integration to the evaluation of physical properties and characteristics.
Key terms
- Flexible electronics
- A technical field covering soft electronic devices and circuits that can be used even when bent
- Self-assembly
- Many organic substances have the property of forming organized structures on their own. This is one of the major advantages that inorganic substances lack.
- Stretchable
- Able to be used even when stretched and compressed, like rubber

ResearchResearch themes
Organic materials have a relatively simple composition, built on a skeleton of carbon atoms, yet they have extremely excellent properties and functions. Applying this diversity and multifunctionality, the lab conducts research and development on soft electronic devices and on organic electronics and photonics.
*Illustrative imageOrganic devices using self-assembly
Using the self-assembly of organic molecules, the lab aims to develop new thin-film devices by programming single molecules a few nanometers long and arranging them finely and regularly.
*Illustrative imagePrinting and integration of organic electronics
Many organic materials can be made into solutions and printed over large areas by methods such as inkjet printing, which also keeps material consumption low. Building on its work introducing printing technology to the fabrication of organic transistor integrated circuits, the lab aims to model organic printed transistors and create new types of devices.
*Illustrative imageStretchable electronics with nanomaterials
Using its original technology for dispersing carbon nanotubes uniformly in rubber, the lab developed a stretchable conductor that stretches like rubber and conducts electricity like metal. It aims to realize stretchable organic electronics that can cover curved surfaces and moving parts.
*Illustrative imageDeveloping soft biosignal sensors
Using soft electronics such as organic process technology and stretchable wiring technology, the lab develops sensor systems that are gentle on the human body. It integrates technologies for low-power integrated circuit design, highly reliable communication system design, and advanced information processing.
