For the last 4 years, we've been working on improving the efficiency of deep sleep. This isn't more time spent in deep sleep, it's increasing the synchronous firing of neurons which are the driver of slow-waves, which define deep sleep. We've got working devices and are going through the ethics approval to continue testing on a larger group of people before we're able to confidently bring our solution to market. I find it useful myself atm, I think it has the largest potential impact of any project I've worked on before. (https://affectablesleep.com https://affectablesleep.com).
