Power from Pressure: Understanding Piezoelectricity

Definition

Piezoelectricity is a fascinating phenomenon where materials like quartz and lead zirconate titanate (PZT) generate electric charges when squeezed or stressed.

Characteristics

1. The uneven charging of atoms in these materials due to pressure results in a small electric current.
2. Materials that convert electric currents into physical movements are commonly used in sensors and accelerometers due to their ability to convert mechanical signals into electrical ones.
3. Quartz watches have gained popularity and affordability due to their use of this technology in their functionality.
4. "Piezoelectric" is derived from Greek words meaning "to squeeze" and amber's association with static electricity.
