Flexible smartphones are going to become very popular in the future. You can’t buy one from Apple or other major smartphone makers yet though. The FlexPhone is a smartphone prototype with a full color flexible display and flexible sensors. It functions as a regular phone but can be rolled up onto your wrist to act as a fitness monitor.
Royole’s FlexPhone can monitor your heart rate, steps taken, and distance. It is 6mm thick and about 100g in weight. The phone has 3G connectivity and will run Android. Pretty cool, don’t you think?
