piezosüütaja

A piezosüütaja, also known as a piezoelectric igniter, is a device that uses the piezoelectric effect to generate a spark. This effect occurs when certain crystalline materials, such as quartz or certain ceramics, are subjected to mechanical stress. The stress causes a temporary charge separation within the crystal, leading to a voltage difference. In a piezosüütaja, this stress is typically applied by a spring-loaded hammer that strikes a piezoelectric crystal.

The rapid impact creates a high voltage across the crystal. This voltage is then directed to a small gap between two electrodes. When the voltage becomes high enough, it causes the air in the gap to ionize, creating a conductive path. This ionization results in a visible spark, which can be used to ignite flammable materials.

Piezosüütajad are commonly found in gas lighters, barbecue grills, and gas stoves. They are a reliable and convenient alternative to matches or other ignition sources. Their operation does not require any external power source like batteries, making them self-sufficient. The simplicity of their design also contributes to their durability and low maintenance requirements. The force applied to the piezoelectric element determines the intensity of the spark.
