With FitBits and Apple watches everywhere, sleep tracking is a wrist glance away. The latest innovation, titled B2v2, goes on your head rather than wrist and is worn for a matter of minutes. B2v2 uses proprietary algorithms to convert brainwaves from the frontal poles and temporal lobes into music-like tones. As it does this, the device recognizes out-of-balance brainwaves. Once discovered, B2v2 plays these waves back for your brain to recognize what is out of balance so it may correct itself. This allows the user to be more relaxed, sleep better, rid stress, and have improved feelings of wellness. While it has a Wonder Woman look to it, the B2v2 does wonders for your peace of mind.
