“Can we make energy by just walking on floor tiles?”

 

The ground floor of a building is typically thought of being statics and unuseful. But can we use our engineering mindset to change this? Well, energy generation often requires some sort of change of state in a system to happen. And in buildings, one change that is always happening is people’s movement. Specifically, people seem to be stepping everywhere to get somewhere. With this motion, pressure is exerted on the ground of a building. And if we take a note from our knowledge of circuits, then we know that we can create an electric current through this pressure with piezoelectricity. Therefore, if we implement piezoelectric tiles in a building, we can create a Piezoelectric Energy Harvesting framework. Researchers at San Jose State University are studying this field, and are hoping to implement a working piezoelectric tile by the end of Spring 2019.
