Mechanical pressure is then applied to the material by the metal plates, which forces the electric charges within the crystal out of balance.At this point, the material is in perfect balance and does not conduct an electric current. A piezoelectric crystal is placed between two metal plates.You can apply mechanical or electrical energy to the same piezoelectric material and get the opposite result.Īpplying mechanical energy to a crystal is a direct piezoelectric effect and works like this: The most unique trait of this effect is that it works two ways. We have specific materials suited for piezoelectricity applications, but how exactly does the process work? With the Piezoelectric Effect. Lithium Niobate is a material that combines oxygen, lithium, and niobium together in a ceramic material that performs similarly to barium titanate.Barium Titanate is a ceramic piezoelectric material discovered during World War II and is known for its long-lasting durability.PZT is from lead zirconate titanate and can produce more voltage than quartz with the same mechanical pressure.Man-made piezoelectric materials include: Other naturally occurring piezoelectric materials include cane sugar, Rochelle salt, topaz, tourmaline, and even bone.Īs piezoelectric technology started to take off after World War I, we began developing man-made materials to rival the performance of quartz. The most well-known, and the first piezoelectric material used in electronic devices is the quartz crystal. There are a variety of piezoelectric materials that can conduct an electric current, both man-made and natural. If you take the same piezoelectric crystal and apply an electric current to it, the crystal will expand and contract, converting electrical energy into mechanical energy. However, if you apply mechanical pressure to a piezoelectric crystal, the structure deforms, atoms push around, and you have a crystal that conducts an electrical current. The structure in these crystals isn’t symmetrical, but they still exist in an electrically neutral balance. There are other crystals that get lumped together as piezoelectric materials. This makes them useless for piezoelectric purposes. Most crystals, such as iron, have a symmetrical unit cell. Regular crystals are defined by their organized and repeating structure of atoms that are held together by bonds, called a unit cell. In a nutshell, piezoelectricity is the process of using crystals to convert mechanical energy into electrical energy or vice versa. Instead of squeezing grapes to make wine, we’re squeezing crystals to make an electric current! Piezoelectricity is in a ton of everyday electronic devices, from quartz watches to speakers and microphones. The word piezoelectric originates from the Greek word piezein, which literally means to squeeze or press. Piezo what? Piezoelectricity sounds like a lot to take in, but it’s simple to understand.

Learn how piezoelectricity produces an electric charge by applying mechanical stress to a piezoelectric material. On top of that, the lighter for the gas burner is rechargeable, and every charge will last a fair amount of time.Français (French ) Italiano (Italian ) Deutsch (German ) The firelighter for the kitchen can also be used to light up candles or oil burners, helping craft the right atmosphere for the establishment. Just pick up cooking gas lighter whenever they find themselves in the mood for cooking. They won't have to worry about running out of matches again. Those who spend most of their time in the kitchen, then they will benefit a lot from a long kitchen lighter. The battery lighter for the kitchen is suitable for home use, as well as restaurants and cafes. Unlike regular matches, a kitchen flame lighter provides some distance from the stove, which decreases the odds of burning oneself while lighting up the stove. An electric kitchen lighter can be used in various gas stoves, ovens, and barbeque grills.

With piezoelectric lighter, this will no longer be a problem.Ī refillable kitchen lighter is a tool people can count on because the user can easily change the battery whenever it runs low. There's no need to make countless trips to the convenience store to buy matches. The cooking process becomes more convenient with our assortment of wholesale piezoelectric lighter.
