Profile
Cellulose nanofiber materials, ISIR, Osaka University
Cellulose nanofibers with 4-20 nm width are bundles of cellulose microfibrils, which are frameworks of cell walls in all the plants. We have developed nano-fibrillation processes of bio-resources (wood, plants fibers, crabs, shrimps e.t.c.) and some advanced nanofiber materials with high optical transparency. Moreover, we have also improved their properties or processes to realize their applications in the electronic devices.

Thermoelectric Energy Harvesting 2018-2028: Applications, Markets, Players

IDTechEx Report: Dr Peter Harrop and Mr Raghu Das
5 Feb

A simple new approach to plastic solar cells

Plastic solar cells, based on blends of conducting organic polymers, are of interest for making lightweight and cheap solar cells. The problem with these kinds of solar cells is that their solar power efficiencies are very closely related to the way the different types of materials mix and crystalize in thin films. This means complex and careful processing is usually needed to make efficient polymer solar cells.

EEG headset for emotion detection

Traditionally, EEG brain scans are used to diagnose medical conditions such as epilepsy or sleep disorders. More recently, EEG brain scans have been introduced as a way to detect emotions which opens doors beyond the medical field. Researchers are looking into e-learning applications, and developers of virtual games are exploring the possibilities of emotion-based e-gaming. Such application domains require real-time emotion detection, which can be achieved through wireless EEG headsets.

Technique to allow AI to learn words in the flow of dialogue developed

A group of researchers at Osaka University has developed a new method for dialogue systems. This new method, lexical acquisition through implicit confirmation, is a method for a computer to acquire the category of an unknown word over multiple dialogues by confirming whether or not its predictions are correct in the flow of conversation.
