Harnessing every step: exploring how piezoelectric materials could illuminate our streets

Understanding Piezoelectric Materials

Piezoelectric materials are unique in their ability to convert mechanical stress into electrical energy. This phenomenon, known as piezoelectricity, occurs when certain materials experience deformation causing an electric charge to accumulate on their surfaces. Quartz, certain ceramics, and even some polymers exemplify materials with these fascinating properties.

The generation of energy from piezoelectric materials hinges on their ability to respond to mechanical pressure or vibrations, commonly applied in areas with constant motion or stress. For instance, when people walk on specially designed piezoelectric floors, their footsteps generate mechanical stress, subsequently becoming a source of electrical energy. This seemingly small conversion can add to considerable energy generation over time, especially in high-traffic urban areas.
