Samsung has quite the diverse family of products, and for the last two years, a team of engineers have been working on yet another. Folks from its smartphone and washing machine teams are building a wearable sensor that monitors brainwaves to detect the early stages of a stroke. The result is a prototype known as the Early Detection Sensor and Algorithm Package (EDSAP): a device that keeps tabs on the electric impulses of the brain with the help of a smartphone or tablet. In theory, the sensor-packed headset will alert folks who are at risk for a stroke early on, so they can get to a doctor to prevent potentially serious and permanent effects. The EDSAP's tech collects brainwave info and beams it wirelessly to the companion device, determining the chances of a stroke within 60 seconds. What's more, when used for longer sessions, the setup can analyze neurological health in terms of stress, anxiety and sleep patterns.
