Piezoelectric electrogenerating footwear

There is an another fun useful application of the piezoelectrical phenomena.

Lets take a look at common shoes. They commonly use elastic soles for a dumping moving effect during walking/running.

Imagine the same shoes, but with piezoelectric elements on its sole (just same as in the piezoelectric lighter) with the ability to produce charge at any type of tension – compression or stretching.

Along with dumping effect they will produce a lot of electricity when moving, which can be gathered and collected lets say in attached accumulator and used for example for charging phones and devices, lighting, etc.
