A golf club head includes a club face with at least one impact sensor, where the sensor has a passive piezoelectric element that is integrated into the club face, the passive piezoelectric element being able to generate a signal when an impact force is applied to the club face. An energy storage assembly includes a battery, a capacitor, or both. An energy harvesting assembly includes a signal divider with at least one input and at least two outputs, the at least two outputs providing a known ratio of a given input signal, wherein the at least one input of the signal divider is electrically coupled to one or more of the piezoelectric elements and a first of the at least two signal divider outputs is electrically coupled to the energy storage assembly. |

1. A golf club head comprising:
a club face with at least one impact sensor, the at least one sensor including a passive piezoelectric element and being integrated into the club face, the at least one sensor operable to generate an impact signal when an impact force is applied to the club face, wherein the impact signal is generated during an entire duration of the impact force applied to the club face; an energy storage assembly including at least one of a battery and a capacitor; an energy harvesting assembly including a signal divider with at least one input and at least two outputs, the at least two outputs providing a ratio of the impact signal, wherein:
(1) the at least one input of the signal divider is electrically coupled to the at least one sensor, and(2) a first of the at least two outputs of the signal divider is electrically coupled to the energy storage assembly; and a signal processing assembly electrically coupled to a second of the at least two outputs of the signal divider and to an acceleration measurement assembly, wherein the signal processing assembly is operable to process signals, including at least one of sampling, digitizing, storing, formatting, and wireless transmission. |
