one of the most important equipment in our house that is used on daily basis.so it is important to know about the discovery of this amazing product.the kitchen gas lighter was invented by CURIE.It works on the principle of piezoelectricity.A piezoelectric crystal is the heart of gas igniter.when a strong force is applied on it by means of a spring loaded hammer it produces an electric spark.certain dielectric materials have an internal crystalline structure which when subjected to mechanical stress produces an electric field .These materials are termed as piezoelectric crystals and this principle is termed as piezoelectricity.
piezoelectric spark producers are small devices used both in LPG and cigrette lighters.
