A group of developers within Samsung is developing an algorithm that uses brain signals to predict the risk of a stroke. The brain signals that Samsung receives can be read with a smartphone.
Samsung calls its technology the Early Detection Sensor & Algorithm Package. It consists of software and a headset with sensors that a user must place on their head. The headset measures electrical signals from the brain, which can then be passed on to a smartphone. Based on the pattern of these signals, the smartphone can determine the risk of a stroke and possibly issue a warning.
According to the manufacturer, the algorithm only needs 60 seconds to determine the chance of a stroke. That’s significantly shorter than equipment currently used in hospitals, Samsung said. Incidentally, the technology would also make it possible to provide the user with other information such as sleep patterns, stress level and ‘neurological health’.
The manufacturer also states that the necessary headset with sensors is easy to wear. The algorithm used is said to have been validated by using the data of a large number of patients who have experienced a stroke.
The EDSAP algorithm should also be used in the future for analysis of signals originating from the heart. Because such electrical signals are stronger than those of the brain, Samsung expects to be successful in this area as well.
