Piezoelectric Floor Tiles - Harvesting energy from pedestrians

Piezoelectric tiles, from Kinetic Tiles

There have been many studies looking into harnessing the energy of pedestrians walking through busy public spaces. The conclusions are all similar: it is possible to harvest some of this energy, but the efficiency is quite low. Unfortunately, it seems piezoelectric tiles won't be powering our lights in the near future.
On the other hand, piezoelectric tiles can work fantastically well as self-powered sensors, tracking the movement of people through these public spaces. For those interested in getting a better picture of foot traffic and movement patterns, piezoelectric tiles could be quite useful!

The following links lead to some interesting papers related to the topic. If you've been considering a similar project, these may help guide you in the right direction:

If you're not ready to dive into journal articles, these news stories provide a good layman's look at real world application of piezoelectric tiles. Back in 2008, a power generating floor was installed in a Japanese train station. More than 400,000 people walk through the station daily, yet the tiles may only provide enough electricity to power some of the LED lighting.
