How it works: Electric spark of the ligthers

Anyone know how it works, how it's created that spark found on the lighters, cigarette lighter and on the stove ligthter. like the beating of two metals

thanks.

Vell, you've got your flint on steel and then some piezo HV sparkers.

George H. did ya try google?
 
Flint (aka quartz) on steel is NOT how lighters work: the
non-steel bit is a mischmetal (rare earth) compound that
is ever-so-slightly pyrophoric.

The piezoelectric types use stressed ceramic elements,
I think... and you can buy an igniter for testing anywhere
BBQ grills are sold (the spark assembly is a common
replacement item).
 
I correct my question.
I want know some technical data as the output voltage, if it is possible to use in electrical circuits and if someone has already built some experience using the spark.
Anyone have any comments about it.

Piezos are used as the "needle" in cheap record players.

The forces there only generate millivolts.

Most people start with an *application*
and look for a gadget to do that.
You are trying to back into the process.
I think this is called Materials Engineering.
....or maybe Marketing.

I doubt you could make anything out of an electric spark lighter, excepted
maybe a prank shocker.

ESD tester?

Discwasher used to sell a handheld air ionizer based on a corona point
attached to a piezo element--you pulled on the handle and it sprayed
ionized air.

test and measure. About 1 kV /mm.

They are used for igniting the charge of spud cannons.

I use one to check the operation and sensitivity of a lightening
detector.

With all I'm reading about "energy harvesting" it might be practical
to hack one with something like a pair of masses to work on the pile
and use vibration to generate power.

Seismic detectors? Driveway alert?

Killer phono cartridge. Maybe operate a transformer/speaker with no
amplifier. Impractical due to weight for sure.

I seem to remember the old crystal cartridges to output in the 100++
millivolt range and magnetic to be an order of magnitude lower.
 
Very good this answer, I don't found a material like this when I seached in portuguese in Brazil. Really very interesting Thank you.

For piezoelectric sparkers, search also on

"Lead Zirconate Titanate" also called "PZT ceramic".
"piezo ceramic"
"piezo energy harvesting"

One source of small quantities has been the eBay page of http://www.steminc..com/
See their product "piezo bimorph" also "piezo generator"
