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.
