Samsung engineers are undoubtedly interested in EEG. Following their research on brainwave technology to find an alternative way of interaction with mobile devices, now they announced a prototype device, named as the Early Detection Sensor & Algorithm Package (EDSAP), which can warn about impending strokes. The prototype device monitors brainwaves to detect early signs of strokes and alarms a user through a smartphone or tablet app.Reported by Samsung Tomorrow (the company’s official blog), the project started at Samsung’s Creative Lab (or C-Lab) two years ago when five engineers grouped together to look into the problems of stroke. Samsung C-Lab helps its employees in turning creative ideas into potentially viable products. Apart from warning about possible strokes, the system can also monitor sleep and stress patterns. Now, the team is looking at how it can monitor heart.

There are two parts of the system; a headset with inbuilt sensors which records electrical impulses from brain, and an app which analyses the data in less than a minute using an algorithm and determines the likelihood of a stroke. The sensors placed on the headset collect and wirelessly transmit brainwave data to a mobile app, where the algorithm analyzes the brainwaves and ultimately determines the likelihood of a stroke, all within a 60-second time span. According to the engineers, the EDSAP sensors are able to monitor and analyze brainwaves much faster than the 15 minutes or so required for existing brainwave monitoring equipments at hospitals.

The sensors are able to scan brainwaves in comprehensive detail, thanks to the highly conductive rubber-like material discovered by Se-hoon Lim, the project lead and his team. The sensors are easy to wear. Saline solutions no longer need to be rubbed into the hair, removing the unpleasantries that had previously been a part of brainwave scanning. More importantly, in part thanks to the rubber-like material, EDSAP sensors can be scaled down into a variety of form factors reminiscent of everyday objects. While the current prototype is in the form of a head gear, EDSAP sensors can also be pasted onto the backside of hairpins or eyeglass temples, thereby allowing users to monitor their brainwaves over longer periods of time without the outmoded appearance.

Joe Korner, Director of External Affairs at the Stroke Association said, “Stroke is not inevitable. In many cases there are simple steps people can take to reduce their risk of stroke such as keeping their blood pressure under control, eating a balanced diet and exercising more. Anyone with any concerns about their risk of stroke should have a chat with their GP.“
