ARTIFICIAL SKINS: New concept for artificial skins has been realized by employing liquid crystal-on-organic field effect transistor (LC-on-OFET) structure. This brand-new devices could detect extremely low external stimulation that cannot be sensed by human skin. Our aim with this device structure is to develop ARTIFICIAL SKINS for HUMANOID ROBOTS and ultrasensitive tactile sensors:

ORGANIC MEMORY: Organic Memory is an exciting next generation data storage platform because of their expectations for ultrathin/flexible plastic memory modules. We invented new concept "Organic Field-Effect Memory Transistors with Polymer Energy Well Structure (OFEmT-PEW)" which enables stable data writing/reading and erasing/reading functions. New device structures are being developed:

Strong OLED Materials: Although Organic Light-Emitting Devices are commercialized for displays in smart phones and TV sets, their durability/reliability is still behind the requirement for HD TV sets. Recently we invented new class of organic materials for highly stable OLEDs, which are extremely stable even at 473 K. More materials for strong Organic Lightings and OLEDs:

All-Polymer Solar Cells: Organic Solar Cells are flying high as the strongest candidate for next generation solar cells. We are striving to achieve high efficiency all-polymer solar cells by synthesizing new polymers and by developing new device structures. Our strategy is to make simple-structured semiconducting polymers and/or small molecules in order to get high chances for commercialization:
