Piezoelectric Concept Backpack

This is a simple application for an interesting power-generating technology.

"Shoulder straps made of polyvinylidene fluoride (PVDF), a strong, flexible material that feels similar to nylon, are piezoelectric, which means that an applied stress generates an electrical charge (just like when you rub your feet on the carpet and shock your baby sister). Converting otherwise wasted, ambient energy into electrical energy, there's virtually no difference in the feel or characteristics of PVDF versus normal nylon. Now, all the rubbing of your backpack straps on your shoulders could finally be put to good use and you can leave heavy batteries and bulky chargers at home."
