around sleep deprivation(睡眠不足)Jason Donahue，Ben Rubin and Eric Shashoua were working late nights in Brown's business and engineering schoolsand began thinking about ways to sleep better.They discovered they weren't alone in burning the midnight oil.Around 20% of Americans get less than six hours of rest a night.The friends imagined a smart alarm clock that could track how much time we spend in the most restorative(促使康復(fù)的)stages of the sleep cycle：REM(快速眼動(dòng))and deep sleep.What would it cost to design such a thing？Five years of research,20 employees，$14 million in funding and a lot of doubting from investors and scientists.The company，Zeo，based in Newton，Mass.，launched its product in June.The Zeo device uses a headband with tiny sensors(傳感器)that scan your brain for signs of four sleep states：REM，light，deep and waking sleep.The smart alarm clock displays a graph of your sleep pattern and wakes you as you're transitioning out of REM sleep(which is when you're least sleepy)In the morning you can upload the data to the company's website，and so track your sleep over time.The cost，$399，includes six months' access to one of Zeo's online sleep coaches.Most of the feedback(反饋)comes in the form of Zeo's ZQ score showing how well you've slept.“Zeo allows people to unlock this black box of sleep，”says Dave Dickinson，a health­care CEO.Whether any of this actually improves sleep is up to the consumer，who will also need to make lifestyle changes like cutting out alcohol before bedtime or caffeine after 3 pm.For now the company is selling Zeo online only.Dickinson also plans to expand to countries such as Australia，where sleep deprivation approaches US.levels.1Why did the three students imagine a smart alarm clock?ATo earn enough money for a
