A study has discovered that wrist bands can provide an insight into the users emotions and can change colour depending on the level of the users emotional arousal. Research has been carried out at the Lancaster University in the U K. which showed that smart materials worn on the wrists could diagnose people who are affected by depression, anxiety and bi polar disorders just by monitoring their emotions.

The wrist bands would change colour depending on the level of emotional arousal. The researchers worked with thermochromic materials  that change colour when heated up. Tests were carried out on participants who wore  them when watching movies, playing games, having conversations, laughing, relaxing and becoming scared. A skin response sensor picked up changes through galvanic skin response which measures the electrical conductivity of the skin.
