There was an article on a similar application recently in Design News.  They

are putting piezo transducers into baseball aluminum baseball bats.  Some of

the shock and vibration that is normally transmitted to the batter's hands
is
now converted to electricity and dissipated as heat in a resistance in the
bat.

I don't know how effective it is, but anyone who has been stung by the
resonance set up in a bat when you nailed the ball may be a potential
customer.
