THE EVOLUTION OF THE TENNIS RACQUET
This is a brief, but quite informative article on the history and evolution of tennis racquets. I must admit I learned some things, not the least of which that the first "racquets" were hands, not actual equipment. And...it take you from the ancient to the ultra-futuristic...mentioning Head's new racquet that uses piezoelectric technology.
Piezoelectric materials convert vibration or motion to and from electrical energy. Head's new racquet takes the vibration resulting from impact with the ball and converts it to electrical energy, which serves to dampen that vibration. A circuit board in the racquet's handle then amplifies that electrical energy and sends it back to the piezoelectric ceramic composites in the frame, causing those materials to stiffen.
We at WhatsAllTheRacquet are looking forward to getting our hands on this to try it out. You all will be the first to know when we do.
