Energy in motion
Every day thousands of people are moving relentlessly producing kinetic energy which ends up dissipated and lost. If we could sum up the movement of each single person we would have a sustainable source to feed many human activities. An effective mechanism to transform the movement into electrical energy is the technology called "piezoelectric". The first studies date back to 1880, when Pierre and Jacques Curie theorized the phenomenon. The operation is expressed in the same word, which means "electric pressure", or the ability of certain crystalline materials to create a potential difference when subjected to mechanical stress. Today is studying ways to use large piezoelectric systems in crowded and highly frequented places. Such as the...
