A board, such as a ski or snowboard, that includes a piezoelectric damper. A sensor such as a piece of piezoelectric material is located on the body of the board such that, as the board vibrates or deforms, the piezoelectric sensor is also deformed. As the piezoelectric sensor deforms, it produces an electrical signal that is provided to a control circuit. The control circuit receives the electrical signal and generates a control signal of proportional amplitude and frequency, but an inverse waveform to the sensed vibration. The control signal causes a piezoelectric damper to stiffen and resist deformation of the board, thus damping the vibration. The sensed signal may also be stored within a memory device and subsequently downloaded to provide a skier profile for analysis.
