Manchester City will sport the latest in wearable technology next season as the humble soccer scarf gets an upgrade, complete with a biometric sensor integrated into the fabric to monitor emotional, physiological and movement data. Using an EmotiBit bio sensor that sits discreetly on the neck, 'The Connected Scarf' captures the body's bio-signals throughout a match. It also records a range of physiological measures, including heart rate, body temperature and emotional responses -- offering information on how fans feel at different moments.
