mini generator?

Question

can anyone tell me more about this thing? becuase the only thing i can find is this article about georgia tech's research on mini generator...
do mini generators generate power by itself? or does it need to be connected with another device?
and is it possible for me to connent motion sensors to the mini generator and have power produced?
thanks alot to anyone who answers me!
