BA Testing 'Happiness Blanket'

British Airways has begun testing a hi-tech blanket which changes colour using brainwaves, to ensure it offers customers the best flight¡¯s sleep in the sky. ? The ¡®happiness blanket¡¯, which is woven with fibre optics, uses neuro-sensors to measure a person¡¯s brainwaves and changes colour, from red to blue, to show when they¡¯re at their most relaxed and meditative.
