Piezo ignition is a type of ignition that is used in portable camping stoves, gas grills and some lighters, and potato cannons. Piezo ignition uses the principle of piezoelectricity, which, in short, is the electric charge that accumulates in some materials in response to high pressure. It consists of a small, spring-loaded hammer which, when a button is pressed, hits a crystal of PZT or quartz crystal. Quartz is piezoelectric, which means that it creates a voltage when deformed. This sudden forceful deformation produces a high voltage and subsequent electrical discharge, which ignites the gas.

Most of the replacement lighters are battery powered. If yours sparks as long as you hold the button down, it's battery powered. Unscrew the button to replace the battery.
Golly, most of the ones I've seen on the cheaper grills are NOT battery powered. If it truly is a Piezo lighter then it just makes a spark from friction.
It was invented by a guy who saw a monk fall and die lighting candles in his church. He went on to invent all soft of safety equipment. The fire alarms in my school were made by the company he founded. The clocks and bells were part of the system. When the school closed I got one of the clocks. It is 50 years old and still keeps perfect time. He also invented the bell that they ring for the start of trading on the stock exchange.
I forget his name unfortunately.
