A new invention is looking to increase workplace productivity. The Doppel band, made by a London-based startup of the same name, is equipped with a vibrating motor that emits vibrations on the user’s wrist. According to the company, the vibrations trigger the body’s natural response to rhythm, helping users stay alert or calm down based on the speed of the vibration. Users regulate the rhythm of the vibrations by tapping on the device or via smartphone app.
