Hi, I wish to adapt your ideas to my invention, StrideDeck, a personal exercise machine in which a person can actually skate on wearing skates.  The platform consists of lines of rollers and are supported by slacks.  The slacks are also used as a bushing.  As the user strides over the platform, causisng the rollers to spin on the slacks, noises and vibrations are produced.  The stronger the force, the louder is the noise and vibration. The piezo wafer is attached to the slack.  The attached piezo was connected  to a mixer and also to an amplifier and I have no results.    Do I need some type of a signal booster?  Any suggestion?  I can email pictures of the StrideDeck if you wish.

thanks,

cadmar
