The friends imagined a smart alarm clock that could track how much time people spend in the most restorative(有恢复作用的) stages of the sleep cycle: REM (rapid eye movement) and deep sleep. What would it cost to design such a thing? Five years of research, 20 employees, $14 million and a whole lot of doubting from investors and scientists.
Their company, Zeo, based in Newton, Mass, launched its product in June, 2009. The Zeo device uses a headband with tiny sensors(传感器) 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 not in REM sleep. In the morning you can upload the data to the company’s Web site, and so track your sleep over time. Most of the feedback(反馈) 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 health-care 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 P.M.
For now the company is selling Zeo online only. Dickinson also plans to spread it to countries such as Australia, where sleep deprivation approaches US levels.
24. Who will support Zeo?
A. People full of imagination.
