In the quest for deep sleep, two Washington University graduates have developed Chrona, a soft foam pad used in a pillow that monitors brain waves via a smartphone, as reported by the Riverfront Times.
Zimin Hang and Ben Bronsther didn’t set out to improve sleep. Like many entrepreneurs before them, the young Washington University grads merely thought they could measure it better.
They wanted to invent a device that would allow sleep research to be conducted in the patient’s own bedroom. Instead of intrusive caps that require study subjects to spend nights wired up in a lab, what about sensor sheets that could be tucked beneath their pillowcases to measure sleep patterns? Perfect the technology, and researchers would surely line up, checkbooks in hand.
