We did a project with some Vernier hand grip monitors (http://www.vernier.com/probes/hgh-bta.html 
) that communicate with their USB device (http://www.vernier.com/go/golink.html 
). We pulled the heart rate outputs into a Flash animation to create  
an abstract audio/visual "orchestra" with different users' inputs.

They've held up well, and are flexible to mount because they're  
wireless. Ours was a prototype for a corporate office, though, so I  
can't vouch for "bullet proof" with kids around...
