[sdiy] Piezo body sensors?

[WeAreAs1 at aol.com]

Hello guys n' gals,

Since we're talking about piezo sensors, I'll bring this up:    Someone has 
asked me to help him build a triggering system with trigger sensors that will 
be mounted on or in his clothing -- his pants, his shirt, etc.   I can't 
imagine that he's the first to think of doing this, so I'm wondering if any of you 
have experience with this, or know someone who has -- or know of any web 
references on the subject.

I'm assuming that we'll use piezo sensors, unless someone comes up with a 
better idea (unfortunately, FSR's are not readily available to DIY'ers).   He 
wants to play the sensors with his bare hands, which should probably work OK with 
piezos.   It's probably a pretty straightforward thing to do, but I would 
like to see how others might have approached mounting the sensors to clothing or 
to arms and legs, and hear about potential problems that we might face.   I 
was thinking that we might hot-glue them onto some thin but stiff sheets of 
plastic or rubber, then sew the sheets into some pockets on the clothing.   Any 
better ideas?

These sensors will most likely be wired up to the electronics from a Roland 
SPD-S sampling drum pad unit, which has inputs for up to 11 trigger sensors.   
It will be part of a very interesting and fun portable electronic performance 
rig that's mounted onto a, umm, one of those, umm... well, one of these:

It'll also have a keyboard stand with two lightweight keyboards mounted just 
above the handlebars, a digital looping system for real-time loop creation, 
built-in battery-powered speakers and amp, and a wireless transmitter to send 
audio to a remote recorder and/or sound system.

The goal is to build a self-contained, self-propelled, battery-powered 21st 
century busking rig that can be used for guerilla electro performances in 
public places, such as parks and malls, where one would not normally expect to find 
such a thing.
