A wearable band that can reads human emotions

A skin response sensor picked up changes in arousal - through galvanic skin response, which measures the electrical conductivity of the skin - and represented it through the various prototype designs. Those smart materials which were both instant and constant and which had a physical rather than visual output were most effective.

"Participants started to pay attention to their in-the-moment emotional responses, realising that their moods had changed quickly and understood what it was that was causing the device to activate. It was not always an emotional response, but sometimes other activities - such as taking part in exercise - could cause a reaction," said Umair.

"One of the most striking findings was that the devices helped participants started to identify emotional responses which they had been unable to beforehand, even after only two days," Umair remarked.
