Mendi is a brain training device.
The gadget consists of a headset that is attached to your head and uses infrared light to measure the tension of your thinking process, or more precisely, your concentration. The higher it is, the more oxygenated your brain is and the "stronger" it becomes.
You can track your results in an app on your smartphone.
