SIMBAND

Samsung has unveiled a prototype wristband that can be fitted with third-party sensors to gather a range of health data about the wearer's body.

Samsung discussed being able to take precise readings for heart rate, blood flow, respiration, galvanic skin response, hydration, and gas and glucose concentrations in the blood among other body readings, as well as data about substances carried in the surrounding air - all on a device no bigger than existing smart watches.

Samsung's even include wi-fi and Bluetooth connectivity in the Simband device.
