Sounds interesting, right?
The piezoelectric effect is a property of some materials to produce an electric charge in response to stress.
However, piezoelectric materials are solid and inflexible, like glass.
When the film is squeezed, the relative charge between the sides changes, and electricity flows.
When the rig is compressed by human motion, or mechanical energy, it creates electrical energy.
The researchers also discovered that the gadget becomes more powerful when folded.
By folding the material over and over, the electricity output can be upped to levels that power gadgets.
Actually, it produced enough power to light 20 LEDs.
Each time you fold it you are increasing exponentially the amount of voltage you are creating, Sepulveda said.
