![]() Older versions īefore piezo-electric lighters became available, gas stove burners were often lit with a flint spark lighter. In gas lighters, piezo-electric ceramics like lead zirconate titanate also known as PZT are used due to their low cost and high sensitivity. This electric discharge is the spark which when exposed to the combustible gas from the stove ignites it to produce flame. Due to high voltage generated, the air is ionized and acts as a path for the discharge. The lighter is wired in such a way that this whole voltage is applied in a small region of air gap between two metallic points. Due to piezo-electric effect, a high voltage is generated in the range of 800 volts. The hammer hits the piezo-electric crystal. When the button is pressed over a limit, the spring releases the hammer. When this button is pressed, the hammer is moved away from the piezo-electric crystal. Piezoelectric devices are much longer lasting than devices that depend on flint. This creates the necessary amount of voltage to generate a spark. This is the typical process used in such lighters. The hammer and spring set up is attached to a button. When the button on a Piezo electric ignitor is pressed, a spring loaded hammer strikes quartz in order to create a spark. ![]() The gas lighter is mostly cylindrical in shape and consists of a piezo-electric crystal over which a spring-loaded hammer is placed. ![]() Tourmaline and quartz are some well known piezo-electric crystals. The crystals which exhibit such property are called piezo-electric crystals. The phenomenon of piezo-electric effect can be briefly explained as follows: when pressure is applied along one axis of a crystal (mechanical axis), a potential difference develops across the transverse axis (electrical axis) of the crystal. It uses a physical phenomenon which is called the piezo-electric effect to generate an electric spark that ignites the combustible gas from the stove’s burner. It is used for gas stoves which do not have automatic ignition systems.
