Ceramics manufacturer and supplierCeramTecis seeing rising demand for piezoelectric (PZT) ceramic components to fulfill sophisticated underwater acoustic applications.
该公司为水下声音声纳应用的被动系统和主动系统生产定制的PZT组件，特别关注半球，碟片，块和管。
“我们看到对大型组件的需求不断增长，这对于某些技术要求的声纳应用是关键，” Paul Turnbull说，UK Ceramtec的Piezoelectric＆Dielectric工程经理Paul Turnbull说。“这包括直径为200毫米至250毫米的圆盘，半球以上的半球以及厚度高于25 mm的压电板。
“Our teams in Ruabon and Southampton as well as in Lauf, Germany, have long-standing and specific expertise in this market segment and specific facilities to manufacture large piezoelectric components which achieve lower frequencies for certain sonar applications, which can mean detection at longer distances.”
开发技术陶瓷
Ceramtec是技术陶瓷的领先开发商，制造商和供应商，产品组合编号超过10,000。该公司的产品在跨越医学工程，汽车，电子，能源和空间的各种行业中发现了用途，仅举几例。
While much of CeramTec’s portfolio isn’t directly related to 3D printing, the firm highlighted theimportance of product diversificationin the release of its FY 2020 financials, citing several upcoming international 3D printing projects.
This year alone, CeramTec has made a number of 3D printing-related developments, including the launch of itsRocar 3D打印粉, which supposedly has similar properties to silicon carbide. Alongside this, the firm released itsCeramCreator tool帮助客户简化其流程链并缩短报价流程。
In the summer, CeramTec successfully tested the cooling capabilities of its newe-mobility power semiconductor moduledeveloped in partnership withFraunhofer IISB,一个d produced a新一代陶瓷样品容器for a space experiment facility on the International Space Station in partnership withAirbus Defence&Space一个d theEuropean Space Agency.
PZT组件的需求不断增加
压电是在某些固体材料（如陶瓷）中积累的电荷，以响应应用机械应力。PTZ组件和材料将机械效应转换为电信号的能力是满足复杂的Sonar技术应用（例如水下声学）的复杂需求和挑战的关键。
For instance, hydrophones and towed arrays require long, thin wall tubes of up to 30 mm length and a wall thickness range from 0.75 mm to more than 2 mm. This specific combination of long and very thin tubes is demanding from a manufacturing perspective, and is a specific area of expertise for CeramTec’s sonar technology team.
CeramTec deploys its advanced manufacturing capabilities to produce numerous other PTZ components, covering the full ranges of Navy Type I, II, III, VI, and other custom formulations. These developments are based on specific requirements for components, transducers, and assemblies.
该公司PTZ组件的典型应用诱导潜水员检测阵列，用于检测石油和天然气沉积物的牵引阵列系统或用于生产活跃和被动声纳系统中的定制1-3复合材料的压电陶瓷板。
现在，Ceramtec观察到对大型组件的需求不断增长，这是许多技术要求的声纳应用的关键。该公司认为，通过其在英国和德国的制造设施来满足这一市场需求是很好的。
Turnball说：“在这个市场领域，没有任何规模适合所有尺寸，我们与我们有长期关系的客户依靠我们和我们内部的研发功能来提供与其规格相匹配的解决方案。”
3D printing PTZ components
Piezoelectric components and materials are receiving increasing interest from the 3D printing sector, due to the potential they hold for a wide array of industries.
该领域最前沿的一家公司是纳米尺寸，用于加性电子产品（AMES）的3D打印机的领先制造商，其AME开发过程是based on piezolectric 3D printing.
在其他地方，来自Virginia Polytechnic Institute and State Universitydeveloped a method to 3D print piezoelectric materials capable of converting mechanical energy into electric current. These piezoelectric materials could then be used as transducers and sensors that responded to pressure, vibrations, and impacts via electric signals.
Most recently, scientists fromJeonbuk National University3D printednovel wearable self-powered sensorsthat could harvest the piezoelectric energy generated by human movement. When built into an array, the sensors could use this charge to detect pressure inputs and convert them into signals.
