👟 Adidas makes World Cup ball a smart device

The official World Cup ball Trionda must be wirelessly charged before each match. It contains a 14-gram motion sensor operating at 500 Hz, tracking position, speed, spin, and direction 500 times per second. A full charge lasts about 6 hours, enough for the entire game including extra time.

Sensor data combines with stadium cameras to create a real-time 3D model of every play. This feeds the VAR room to speed up and improve decisions on offsides, handballs, and goal-line calls. At around $170, Trionda may be the most expensive standard match ball in World Cup history.
