Someya-Jimbo Lab
Machine-translated · View original
A lab that uses soft organic materials to create electronics that blend with the human body.
AboutAbout the lab
Soft bio-organic devices, kind to people
The Someya-Jimbo Lab studies electronics made from soft organic materials and their applications in biology and medicine.
Organic devices can be easily fabricated on plastic, so they are expected to become a new kind of device that is thin, lightweight, and does not break when bent.
Taking advantage of the softness of organic devices, the lab aims to develop new devices that blend electronics with the living body.
Lab meetings are held in English, and the lab carries out research with researchers from a wide range of fields, from electronic engineering and materials to biology and medicine.
Key terms
- Organic device
- An electronic component made from carbon-containing organic materials. It can be fabricated on plastic and is thin, lightweight, and bendable
- Integrated circuit
- An electronic circuit in which many components, such as transistors, are built together on a single substrate
- Nanomesh
- A sheet in which fibers much thinner than a human hair overlap like a net. It is thin and permeable to air and sweat

ResearchResearch themes
The lab studies thin, bendable electronics that take advantage of the lightness and softness of organic materials. It develops devices that are compatible with the human body and is advancing their application to medicine and healthcare.
*Illustrative imageFeather-light, ultrathin electronic circuits
The lab fabricates extremely light and thin integrated circuits of organic transistors, about 2 micrometers thick. The goal is circuits that do not break even when rolled up like paper and that can be attached to curved surfaces such as skin to continuously measure biological signals such as body temperature and blood pressure.
*Illustrative imageUltrathin organic solar cells
The lab studies thin, lightweight organic solar cells by uniformly forming organic semiconductor films on extremely thin polymer films. It has also realized solar cells that do not break when folded small and whose performance does not drop even when they are greatly stretched and compressed.
*Illustrative imageStretchable sensors made with nanomesh
Using nanomesh, in which fine fibers overlap like a net, the lab makes thin, lightweight strain sensors that withstand stretching and compression. They do not hinder movement even when attached to the face, and can measure the fine movements of the face during speech.
