Hey all, I'm a University of Minnesota EE student, doing research on renewable power scavenging from human locomotion.... Anyways, I've been hard pressed to find out anything on the power consumption of the Ipod Nike+ sensor/transmitter.... Do anyone here know the battery spec or power rating for it? Or direct me to some source may know? It'll be a real great help. I believe my project can actually power something like that from walking/running. Thank you all!
