Boston Piezo-Optics specializes in the supply of custom and OEM specified piezoelectric transducer crystals and maintains an inventory of quartz, many of the popular piezoceramics, lithium niobate, tourmaline, and other special piezoelectric materials from which we fabricate crystals to meet your specific needs.
The skills necessary to produce our transducer crystals are readily applied to the production of related acoustic items, such as wear plates and buffer rods. High quality lapping techniques and chemically applied overtone polish provide crystal quartz, fused silica and alumina components with minimal sub-surface damage.
Crystals as large as 4\" X 8\" at 1 MHz in quartz, 6\" in diameter in ceramics, and as small as 0.020\" in diameter in both quartz and ceramics are available. Rectangular or square crystals can be made in similar sizes.
Two surface finishes are standard: 3 micron fine lapped for fundamental operation, and our proprietary chemical polish for overtone operation. Note: Overtone polish is available on all our materials. The flatness and parallelism will vary with the material and especially the thickness. We do not quote specific numbers of flatness and parallelism, but we guarantee that the crystals will resonate at the 3rd, 5th and 7th overtones. Some crystals can be made to very specific degrees of flatness and parallelism. This is a function of size. Please request a quotation.
Soldered wire leads, appropriate to the size and frequency of the crystals, are available. Or, we will gladly explain how to make your own soldered connections onto our electrodes. Click here for the instructions.
The Piezoelectric crystal is used in a broad variety of common consumer, commercial, and industrial products. These crystals are used in watches, ultrasound equipment, microphones, cigarette lighters, inkjet printers, speakers, and a wide variety of sensors and motors, among many other applications.
Piezoelectric crystals are capable of the piezoelectric effect, which is the ability of a material to generate an electric charge when subjected to pressure. There are both natural and synthetic materials with this potential.
The process is simple for generating electricity from a piezoelectric crystal that is fairly simple. To turn mechanical energy into electrical energy (the direct piezoelectric effect), metal plates are used to squeeze the crystal. The pressure disturbs the atomic structure and creates an electrical charge which is collected by the plates. More pressure means more electrical power.
The inverse piezoelectric effect is created when the balanced crystal, again placed between two metal plates, is charged with electricity. This essentially forces the crystal to squeeze itself, deforming its structure, which releases a sound wave.
Quartz is probably the most well-known piezoelectric crystal, perhaps because of its use in quartz clocks and watches. However, there are other materials (crystals and others) with this quality found in nature:
Synthetic piezoelectric materials are typically more cost-effective than naturally occurring ones, so manufactured materials like langasite, lithium niobate, barium titanate, potassium niobate, sodium tungstate, lead zirconate titanate (PZT), and others are often used instead of natural crystals. These synthetic options also tend to have stronger piezoelectric potential.
First-time purchasers who are looking to buy piezo electric crystals (irrespective of the number of items being ordered) can expect full assistance and cooperation from our side. In addition to that, we also make sure that all of our products reach our customers only in a matter of few days.
Regular crystals are defined by their organized and repeating structure of atoms that are held together by bonds, called a unit cell. Most crystals, such as iron, have a symmetrical unit cell. This makes them useless for piezoelectric purposes.
There are a variety of piezoelectric materials that can conduct an electric current, both man-made and natural. The most well-known, and the first piezoelectric material used in electronic devices is the quartz crystal. Other naturally occurring piezoelectric materials include cane sugar, Rochelle salt, topaz, tourmaline, and even bone.
We have specific materials suited for piezoelectricity applications, but how exactly does the process work With the Piezoelectric Effect. The most unique trait of this effect is that it works two ways. You can apply mechanical or electrical energy to the same piezoelectric material and get the opposite result.
The inverse piezoelectric effect is used in a variety of applications. Take a speaker, for example, which applies a voltage to a piezoelectric ceramic, causing the material to vibrate the air as sound waves.
Piezoelectricity was first discovered in 1880 by two brothers and French scientists, Jacques and Pierre Curie. While experimenting with various crystals, they discovered that applying mechanical pressure to specific crystals like quartz released an electrical charge. They called this the piezoelectric effect.
The next 30 years saw Piezoelectricity reserved largely for laboratory experiments and further refinement. In World War I, piezoelectricity was used for practical applications in sonar. Sonar works by connecting a voltage to a piezoelectric transmitter. This is the inverse piezoelectric effect in action, which converts electrical energy into mechanical sound waves.
With sonar a success, piezoelectricity gained the eager eyes of the military. World War II advanced the technology even further as researchers from the United States, Russia, and Japan worked to craft new man-made piezoelectric materials called ferroelectrics. This research led to two man-made materials used alongside natural quartz crystal, barium titanate, and lead zirconate titanate.
Actuators use piezoelectricity to power devices like knitting and braille machinery, video cameras, and smartphones. In this system, a metal plate and an actuator device sandwich together a piezoelectric material. Voltage is then applied to the piezoelectric material, which expands and contracts it. This movement causes the actuator to move as well.
Speakers use piezoelectricity to power devices like alarm clocks and other small mechanical devices that require high-quality audio capabilities. These systems take advantage of the inverse piezoelectric effect by converting an audio voltage signal into mechanical energy as sound waves.
Sensors are used in various applications, such as microphones, amplified guitars, and medical imaging equipment. A piezoelectric microphone is used in these devices to detect pressure variations in sound waves, which can then be converted to an electrical signal for processing.
One of the simplest applications for piezoelectricity is the electric cigarette lighter. Pressing the button of the lighter releases a spring-loaded hammer into a piezoelectric crystal. This produces an electrical current that crosses a spark gap to heat and ignite gas. This same piezoelectric power system is used in larger gas burners and oven ranges.
Piezoelectric crystals are perfect for applications that require precise accuracy, such as the movement of a motor. In these devices, the piezoelectric material receives an electric signal, which is then converted into mechanical energy to force a ceramic plate to move.
What does the future hold for piezoelectricity The possibilities abound. One popular idea inventors are throwing around is using piezoelectricity for energy harvesting. Imagine having piezoelectric devices in your smartphone that could be activated from the simple movement of your body to keep them charged.
You can buy piezoelectric crystals from a variety of places online,from searching for \"piezoelectric\" on ebay.com or your country's version of ebay, other marketplacesor commercial manufacturers and retailers.
You might be able to find a piezoelectric crystal in a microwaveoven as well. If your microwave oven makes a beeping sound when food is ready then it may have a piezo speaker inside. If the microwave oven has a dial-type of timer that makes a bell ringing sound then it doesn'thave a piezo speaker. On the second half of mypage about crystal earphones I show how to get one of thesefrom a microwave oven.
The novel material is both electrostrictive and piezoelectric. Its electrostrictive properties means it can change shape when an electric current is applied, while piezoelectric means the material can convert pressure into electric charges.
When an electric field is applied, the atoms that make up electrostrictive materials shift, causing the material to deform and flex. When piezoelectrics are compressed, the pressure is converted to electric charges which accumulate in the material.
The scientists found that when an electric field is applied, the new hybrid material could be strained up to 22 per cent, the highest strain reported in a piezoelectric material so far. This far surpasses conventional piezoelectric materials that only deform up to 0.5 per cent when a current is passed through it. The new material is also more energy-efficient than other piezoelectric and electrostrictive materials.
Piezoelectric materials are commonly used in guitars, loudspeakers, sensors and electric motors. For instance, a piezoelectric pick-up is a device used in an electric guitar to convert the vibrations from the strings into an electric signal, which is then processed for music recording or to be amplified through loudspeakers.
Some ferroelectrics also contain lead, which is toxic, and its presence in piezoelectric devices is one of the reasons why electronic waste is challenging to recycle. Traditional ferroelectrics such as perovskite oxides are also unsuitable for flexible electrical devices that are in contact with the skin, such as wearable biomedical devices that track heart rate.
Prof Fan said, \"Being more than 40 times more flexible than similar electrostrictive materials, the new ferroelectric material may be used in highly efficient devices such as actuators and sensors that flex when an electric field is applied. With its superior piezoelectric properties, the material can also be used in mechanical devices that harvest energy when bent, which will be useful to recharge wearable devices. 59ce067264
