Piezo ignition

Method of igniting camping stoves

Piezo ignition is a type of ignition that is used in portable camping stoves, gas grills and some lighters. Piezo ignition uses the principle of piezoelectricity, which, in short, is the electric charge that accumulates in some materials in response to mechanical deformation. It consists of a small, spring-loaded hammer which, when a button is pressed, hits a crystal of PZT. This sudden forceful deformation produces a high voltage and subsequent electrical discharge, which ignites the gas.
