Elizabeth Redmond is an inventor with big dreams of researching bigger and more complex gadgets. She decided to focus her effort on developing materials that could be used in the generation of piezoelectricity. Piezoelectricity [en.wikipedia.org] is created when certain special materials are compressed or bent by physical force. Elizabeth created a new type of technology called POWERLEAP, which is a flooring that generates electricity when people walk on it. As cool as this is, Elizabeth is setting her sights on even inventive solutions for the world's needs.
