The Otenna smart hair clip invention from Fujistu will let the wearer sense sound through their hair. Created with the hearing impaired in mind, the Otenna is equipped with a microphone that detects the sound’s volume and rhythm, triggering the hair clip to provide haptic feedback. The Otenna can provide up to 256 different feedback levels, alerting the wear to environmental sounds such as a doorbell, person shouting, or even the rhythmic pulse of music.
