There are so many fitness bands right now, and many of them are able to track sleep and such. Given their capability to do so, I wonder if it is possible to extend it for health monitoring. And by this, I mean for acute patients. For example, using the band to differentiate whether the person is conscious or not, whether the person is sleeping or fainting. The band can also be used to know if the person has seizure. It can then be used to see the patter of those events happening.
