I would like to use the Piezo as a MIC and thus seek advice from people out there with more expertise than myself, that have done this before, to advise me on what kind of Piezo would be best suited for the application I would like to use it for. So a Piezo (when used as a buzzer) is selected based on Internal or External drive circuitry as well as the tone (determined by the frequency it emits). Piezo discs are mostly used for buzzers, which emits sound.

Shear mode ceramics offer greater sensitivity and displacement than a piezoelectric ceramic poled and electroded in thickness mode. In addition to APC’s standard line of shear plates, we can custom manufacture shear mode plates and half-rings. APC’s offers a line of standard 15mm x 15mm x 1mm piezo shear plates. APC also supplies piezoelectric ceramics poled in shear mode. Standard and Shear Mode Poling of Piezoelectric CeramicsĪPC’s standard piezoelectric ceramics are poled in thickness mode and electroded on the positive and negative surfaces. Note that due to manufacturing limitations, not every possible dimensional combination above is available. Piezo Cylinder Wall Thickness: Minimum of 0.040” Piezo Cylinder Outer Diameter: 0.350” – 0.900” Piezo Plate Thickness: 0.008” – 0.400” depending on material, length, and width Piezo Ring Thickness: 0.008” – 0.400” depending on material Piezo Ring Inner Diameter: 0.070” – 0.750” depending on OD & thickness Piezo Disc Thickness: 0.008” – 0.400” depending on Material Piezoelectric Ceramic Crystals: Common Shapes and Sizes We are happy to assist you with standard orders and custom requests. To request a quote or to inquire about APC International’s custom piezoelectric element manufacturing capabilities please contact your APC International Representative. Please be assured that regardless of the shape and size of the piezoelectric ceramic you need, when you choose APC International as your supplier the quality is guaranteed. To inquire about the full range of our manufacturing capabilities please contact your APC International Representative. Contact us today to get your order completed quickly!ĪPC International’s manufacturing capabilities extend well beyond what is listed below and that we frequently manufacture larger, smaller, thicker, and thinner ceramic elements for our customers. Ceramic elements listed on this page can usually be delivered with a shorter lead-time than other ceramic elements manufactured by APC International. We have created this page to provide our customers with some background on the more common ceramic shapes manufactured by APC International. We can work with you to create the correct shape and size for you. If you don’t see the shapes you are looking for listed on this page then, please contact us for more information. While these are the most common ceramic crystal shapes manufactured by our machine shop, we also have a great deal of experience manufacturing hemispheres, trapezoids, concave lenses, and other customer specified shapes. APC International most frequently manufactures piezoelectric discs, piezo rings, piezo plates, and piezo tubes (cylinders). Using CNC technology APC International is able to manufacture piezoelectric ceramic elements in a wide range of shapes and sizes.
