1. of or relating to the generation of electric charge by mechanical pressure on certain crystals or ceramics
Usage: technical; often used in compound terms like 'piezo effect' or 'piezo element'

1. a piezoelectric device or component that converts mechanical stress into electrical signals or vice versa
Usage: technical; short for piezoelectric device

Examples

• The lighter uses a piezo igniter to create a spark.
• Piezo sensors are commonly found in modern smartphones.
• The piezo element vibrates when an electric current is applied.
• Many ultrasound machines rely on piezo technology.
• The piezo buzzer produces sound through rapid vibrations.
• Piezo actuators are used in precision positioning systems.
