A few years ago, a team of engineers at Samsung started working on a project to detect strokes by analysing brain waves.
Considered pretty much impossible at the time, they now built a real prototype called the EDSAP for Early Detection Sensor & Algorithm Package. This device allows everyone who has a smartphone or a tablet to monitor the electrical impulses in their brain and therefore give them the chance to detect an oncoming stroke and see their doctor before it happens.
With 15 million people suffering from stroke every year, and 66% of them resulting in death or permanent physical disabilities, this device could be really helpful.
How does it work?
The headset is composed of sensors that wirelessly transmit data to a mobile app where the algorithm calculates the risk of stroke all in 60s. Besides, the data collected can also be analysed to inform the user about stress level, anxiety and sleep patterns.
How does it defer to any other brain sensor?
- Unlike other brain sensors on the market, the EDSAP is more focused on health-related matters rather than controlling other devices.
- It is also a lot faster than the normal time required from the material used in hospitals (60s instead of 15min).
- The highly conductive rubber-like material invented by the team allows the headset to scan brain waves in a larger amount and more comprehensively.
- It is easier and more comfortable to wear as the Saline usually required does not need to be rubbed in the hair anymore.
- Last but not least, the rubber-liked material invented allows the creation of multiple smaller devices that could be implemented in people’s everyday life. For example, for a longer use, the sensors could be added to hairpins or eye glasses.
Based on the analysis of brain waves from patients suffering from stroke combined with Artificial Intelligence, this project, once ready, could also be applied to other neurological health issues such as depression.
