1. A golf club distributed impact sensor system configured to detect impact of a golf ball with a club face, the system including:

  • a non-conducting monolith within the club face of the golf club;

    a plurality of piezoelectric elements within the non-conducting monolith, including at least first and second piezoelectric elements under static pressure; and

    pressure sampling circuitry coupled to the plurality of piezoelectric elements that captures positive and negative pressure values output from the first and second piezoelectric elements, wherein the positive and negative pressure values are simultaneously captured over a plurality of sample points in time during impact of the golf ball with the club face, and wherein the positive and negative pressure values are used to build a time-varying impact pressure profile of the impact to the golf ball.
