How does lighter spark work

My brother found a piece of flint at the railroad track. I bet tomorrow's wwotd will be about why are there so many bugs. Austin Mrs.

Thought-I never knew that a German scientist envinted a lighter. Connection-I hate it when you try to strike a lighter then you get a blister.

Prediction-I bet tomorrow's Wonder will be about bugs. Liz Mrs. I never knew how lighters were made but now I know. I really don't like lighters but it is intristing how there made. The light hurt my eyes. I predict were going to learn about bugs. Connection:I always like to blow out birthday candles. Prediction:I bet tomorrows wonder is about bugs.

Way to go, Liz and carlie! Megan Mrs. Thought:I never knew who invented the lighter but now I do. Connection:My dad will use his lighter to light my candle. Prediction:I think tomorrows wonder will be about bugs. We are so glad you joined the discussion, zane and Megan! Zander mrs. Hello there, arijandra and Zander! Thanks for sharing your comments with us! I think the wonder of the day tomorrow is a new bug they discover.

Kalyn Mrs. Thought: I've always wondered how you lighted a match. Connection: I don't really like fire unless it's on my candles!

Prediction: I bet tomorrow's Wonder will be about bugs. We love hearing from you, tyriq and Kalyn! We hope you'll stop by again soon! Alex Mrs Murphy's class Aug 19, I didn't know it was made in ! I see a lot of disposable lighters at gas stations.

Tomorrows wonder is about bugs. Disposable is a one use thing you throw away. Destinee Aug 19, Thanks for sharing your thoughts, Alex and Destinee!

These voltage changes are amplified and used to record or transmit sounds. Piezoelectric materials also work the other way -- if you apply a voltage across the crystal, the crystal will change shape.

The change is very slight in most cases, but it is enough to drive small speakers. For example, if you have a digital watch with a beeping alarm, the beeper is a little piezoelectric speaker.

Piezoelectric devices are much longer lasting than devices that depend on flint. Quartz is a durable material and is hardly affected when it is struck by the small spring loaded hammer. At the same time, this process creates enough energy to produce a spark. Unlike flint, quartz can be struck thousands of times without showing much wear at all. For frequent use, these lighters provide the most efficient and effective option.

This entire process gets completed in a second or two and the momentum generated by the thumb is strong enough to create a 7kV voltage spark that lights the air-gas mixture near the burner. A piezoelectric crystal is the heart of the 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 and vice versa.

The degree of electric field produced is directly proportional to the magnitude of force applied. These materials are termed as piezoelectric crystals and this principle is termed as piezoelectricity.

Encased in a steel structure, piezoelectric gas lighters are usually in a tubular form as shown in the image above. At the top is a push button made up of steel inside which is present a spring loaded hammer.

When pressed it produces the necessary force needed to generate electric potential in the piezoelectric crystal. Two small handles are provided which helps in gripping the lighter when pressing the hammer with the thumb. The internal view of the tubular rod will clear the mechanism of spark production.

The image above shows the bottom part of the gas lighter. This part is known as ignition head. The ignition head contains a thin metal rod covered with the plastic casing. When the hammer is pressed, a spark is produced at the corner of the metal rod.

Interestingly the position of the produced spark varies each time hammer is pushed down. On opening the steel casing structure from near the top handle a plastic tubular structure comes out which contains the hammer and spring assembly.
