Sony patent application puts electrodes in a pillow, eases you out of slumber

You could monitor your sleep using the science of actigraphy but, as we've learned, accelerometers don't always make for the best slumber trackers. The real deal stuff, used by scientists, requires all sorts of electrodes, which are a tad cumbersome and tend to yank out hair. Sony is proposing a system that removes the glue and sticks the sensors in your pillow. This is according to a patent application the company filed that proposes, among other things, an advanced alarm clock that monitors brain waves to detect when you enter and leave REM sleep. One particular example has it guiding users though an efficient power nap, by starting a timer once they've started dozing and only waking them once they've come out of a deeper sleep state. The proposed alarm could take any number of forms, from a buzzer, to a flashing light or bed shaking motor. To dig through the application for yourself hit up the source link.
