Recently, a wearable LED panel - Fos appeared on Kickstarter. According to reports, Fos is lighter in weight, only about half of the golf ball, plus it can be attached to any desired place, so it is easy to carry. According to the R&D team, Fos wirelessly accepts animation display commands from smartphones. For example, runners can use it to show their heart rate; bikers can use it to show how fast they are riding. 
They also said that Fos can also be used with navigation software, so that the rider can see the route of travel very intuitively, and the light it emits ensures its safety in the dark.
Each Fos panel has a set of white or blue LEDs, a microprocessor, flash memory, and power. It is reported that the 11x3 inch Fos is currently priced at $ 149, and the project's target start-up capital is 200,000 US dollars.
