I heard about this through the New Scientist Twitter feed: Embrace is a smartwatch which is designed to detect changes in electrical signals in the skin that occur before a seizure.
I think I mentioned in a previous post that Ih ave been thinking about getting something like this, but this is much more appealing (and cheaper) than some others I have looked at. It is a crowdsourcing venture and they have been doing offers for below market price ($199) watches for the first few donors. Unfortunately the best offers are sold out, but they are still giving a watch to the first 4000 people who donate $189 (£120) before Christmas (132 taken so far). I think I will do this and thought some of you might be interested, too.
