# It uses a physical phenomenon called "piezo-electric effect" to generate an electric spark which ignites the combustible gas from the stove burner.
The material used is called Piezo Electric Crystal.# If a stress is applied along one axis of the crystal, a voltage develops across a transverse direction.
# In the gas lighter, a spring-loaded hammer gets suddenly released and hits a piezoelectric crystal when the lever or button is presses beyond a limit. This sudden hammering causes a large stress and a high voltage, of the order of "800 volts", gets generated.
# In gas lighters piezoelectric ceramics (like lead zirconate titanate known as PZT) are normally used because of their low cost and high sensitivity.
Next time when u use it , dont forget to recall its principle.
