According to http://www.engadget.com, it’s a smart phone/wristwatch combination that acts as a motion detection unit. The device is only for those who suffer from tonic-clonic seizures, and it’s not a universal seizure detector. However, the company’s clinical trials with the device are ongoing, and Smart Monitor will submit it for FDA approval as a tonic-clonic seizure sensor later this year. For more information:
I have yet to see how helpful this device will be, but I believe that it is a step towards independence for some people with epilepsy. Soon technology may advance to the point where a similar device will be sensitive enough to detect other types of seizures.
