Piezo Power Under pressure, crystals live up to their electric potential

Piezoelectric crystals are materials that generate electricity when squeezed and move when an electric current is applied. Discovered in the 1800s, they have been used in various applications. Today, they are crucial in structural health monitoring, helping ensure the safety of large structures like bridges and airplane wings. In medicine, they can power devices like pacemakers without the need for battery replacement surgeries. Future innovations include integrating these crystals into fabrics and shoes to charge small devices. They are already present in cars, homes, and toys, playing a vital role in everyday technology.
