Affectiva Q Sensor
The Affectiva Q Sensor is a wearable, wireless biosensor that measures emotional arousal via skin conductance, a form of electrodermal activity that grows higher during states such as excitement, attention or anxiety and lower during states such as boredom or relaxation. The sensor also measures temperature and activity.
According to the company: "The curve-shaped Q Sensor is designed to wear on the wrist, so it is comfortable and unobtrusive to wear all day at work, play, or sleep. This makes it ideal for long-term measurement in clinical and therapeutic research."
