The oscillations of a hand-held tennis racket and a racket with its handle firmly clamped were measured by striking the racket with a ball and observing the output voltage from a thin piezoelectric film wrapped around the handle. The oscillations of the racket in these two cases were quite different, with the hand-held racket displaying vibrational modes similar to those of a completely free racket.
