The lab makes solar cells and new devices from soft organic materials.

AboutAbout the lab
Building new systems that take advantage of flexibility.
The Organic Flexible Systems Lab (Fukuda Lab) studies how to build new systems from devices that exploit flexibility, using a range of materials centered on organic materials.
The electronic devices that support today's society are made of hard inorganic materials such as silicon.
Organic materials such as plastics and biological materials, on the other hand, are highly flexible and make it possible to build flexible, soft systems that inorganic electronics cannot achieve.
The lab aims to develop technologies that can be implemented in systems where flexibility is desired, such as wearable electronics and soft robots.
Key terms
- Organic materials
- Materials such as plastics and biological materials. They are highly flexible and are contrasted with hard inorganic materials such as silicon.
- Next-generation solar cells
- Solar cells such as perovskite and organic solar cells. They are attracting attention because they are flexible and can be fabricated by solution coating.
- Active devices
- Devices that go beyond sensors measuring biological information. The lab studies actuators, pumps, stimulation devices, and similar devices.
