A golf ball with a piezoelectric material portion allows golf ball data to be obtained when a golfer hits the golf ball with a golf club. An output from the piezoelectric material generated in response to the impact force of the golf club hitting the golf ball is measured. Based on the measured output, golf ball data can be obtained. The obtained golf ball data may be used by golf club fitting systems, golf ball fitting systems, and golfer profile databases. |
