Samsung has announced that it's working on a
wearable EEG headset that can be used by patients themselves to detect signs of
stroke as well as for regular monitoring to gauge stress levels, analyze sleep,
and other brain health parameters that are often not measured quantitatively.
The Early Detection Sensor & Algorithm Package (EDSAP)
will pair up with a user's smartphone or tablet to display the results of the
ECG tests, which, according to the developers, can be done within about a
Samsung claims that its sensors are able to pickup a much
higher quality signal than current EEG headsets. The material is rubbery in
feel and doesn't require a gel or saline solution to be applied to make a good
electrical connection with the scalp.
On the software side, the company team developed an
algorithm that compares a particular EEG scan against a previous analysis of a
bunch of stroke patient EEG scans. Using signal processing and artificial
intelligence methods, the algorithm aims to spot telltale signs of stroke.
