Electricity from footsteps: Piezoelectric Floors
Have you ever thought of generating electricity from footsteps, an untapped natural resource? Interested? Here are the details of one such clean energy source….. The piezoelectric effect was discovered in 1880 by two French physicists, brothers Pierre and Paul-Jacques Curie, in crystals of quartz, tourmaline and Rochelle salt (potassium sodium tartrate). They took the name from the Greek work piezein, which means "to press" . Piezoelectricity is the ability of certain materials (piezoelectric materials) to produce a voltage when subjected to mechanical stress. Piezoelectricity comes under the concept of ‘Energy Scavenging’. Energy scavenging is defined as capturing minute amounts of energy from one or more of the surrounding energy sources, accumulating them and storing them for later use. In some ways Piezoelectricity is better than solar or wind power because these technologies depend on the weather and are not always reliable. The average person takes 150...
