Adidas made some soccer balls with built-in sensors that can provide data in almost real-time to your phone (ie. take a shot and review ball speed, rotation, point of strike etc...). Video: https://www.youtube.com/watch?v=mpIOnnU1R_o&t=119s (unfortunately no english subtitles).

Also, the technology was used in their latest Euro 2024 ball - the Fussballliebe - to help video referees and their decisions.
