Sensors small enough to fit inside a ball or racket handle are now used in professional and amateur sport.
They track spin, speed, and contact.
In football
Connected ball technology with sensors has been used at major tournaments to help detect the moment of a kick for offside decisions and handball reviews.
Other examples
- ▸Rackets with sensors tracking stroke type and spin
- ▸Smart cricket balls measuring revolutions
- ▸Basketballs with shot-tracking
- ▸Golf clubs and balls with launch data
Benefits
Coaches get objective data, and officials get precise timing. Amateurs can track progress.
Limitations
Sensors must not change how equipment behaves. Data accuracy and battery life matter. See our sports analytics and player tracking guides.
Consumer tech
Amateurs can now buy sensors that clip onto rackets, track golf swings, or analyse basketball shots through a phone camera. Some give useful feedback on consistency and technique. The data is most helpful when paired with coaching, since numbers alone do not always explain how to fix a problem.
