1) Piezoelectric effect:
The ability to generate electric voltage in response to applied mechanical stress”.
The piezoelectric effect is understood as the linear electromechanical interaction between the mechanical and the electrical state in crystalline materials with no inversion symmetry.
The piezoelectric effect is a reversible process in that materials exhibiting the direct piezoelectric effect (the internal generation of electrical charge resulting from an applied mechanical force) also exhibit the reverse piezoelectric effect (the internal generation of a mechanical strain resulting from an applied electrical field).
For example, lead zirconate titanate crystals will generate measurable piezoelectricity when their static structure is deformed by about 0.1% of the original dimension. Conversely, those same crystals will change about 0.1% of their static dimension when an external electric field is applied to the material. The inverse piezoelectric effect is used in production of ultrasonic sound waves.

When a force is applied on piezo crystal 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 and vice versa. Electric field produced is directly proportional to the magnitude of force applied. In Piezo Igniter there are: Ground with case Piezoelectric(Quartz) crystal having a conductor head Spring Hammer in trigger Case |

When we start pushing the push button, it presses the hammer and spring assembly to move in the telescopic shaped plastic casing. At a certain point the spring force is enough to overcome the internal wall force and forces the hammer to move further in and strike the impact pad with a huge force. This mechanical force generated by pressing the hammer assembly causes the crystal to generate voltage which is carried by the electrodes at the ignition head to generate a spark. At the same time by pressing the button there starts a flow of gas from the gas valve, the spark falls on the gas and lights the air-gas mixture. |
