1. A golf club comprising:
- a hollow golf club shaft comprising an exterior and an inner surface;
a golf club grip comprising an exterior and an interior surface coupled to the shaft;
a club head coupled to the shaft, wherein the club head comprises a face, a heel, a toe, a top line, a sole, a hosel, a rear, and a center of gravity;
a first plurality of piezoelectric components selectively positioned along the length of the golf club shaft; and
a second plurality of piezoelectric components positioned within the club head, wherein a first piezoelectric component is located between a toe and a midpoint of the face of the golf club head, a second piezoelectric component is located between a heel and a midpoint of the face of the golf club head, and a third piezoelectric component is located rearward of the center of gravity of the golf club head.

Abstract
An apparatus for determining the kinematic characteristics of a golf club are disclosed. The apparatus includes at least one piezoelectric component selectively positioned within or upon at least one portion of a golf club. When the club head impacts an object such as a golf ball, the piezoelectric component is operable to determine the velocity of the club. It may also be desirable for the piezoelectric component to determine the magnitude of vibration during impact and swing speed. In this manner, the piezoelectric component may function determine the efficiency of a golf club swing.
