The problem with piezoelectric flooring is that the power generated is "stolen" from the person crossing it. Take too much power, e.g. by having a perceptible deformation of the surface, and the person will have the feeling of walking on soft sand or snow and may avoid walking on it. Take too little and the exercise becomes pointless: even with a very generous set of assumptions the PaveGen system produced 1/5000th of a person's power need.
