Muse is a flexible, 4-sensor headband that measures brainwave activity in real-time and sends the data to a smartphone or tablet. It allows users to see how their brain performs under different mental states like relaxation, concentration, and stress. The headband was designed to be comfortable for everyday use and to work with applications for brain health, fitness training, and stress management. In the future, InteraXon aims to use brainwave data to allow users to control devices with their thoughts.
