SBIR Phase I: Cobond/Cofired Capacitor Based Electronics

该小型企业创新研究(SBIR)第一阶段项目将研究与多层陶瓷电容器(MLCC)技术类似的钛酸锆铅(PZT)技术的开发。MLCC设备通常由钛酸钡材料组成，是电子工业中生产和使用最多的电容器，每年的生产量约为1000亿件。然而，作为一种压电材料，钛酸钡已经在很大程度上被PZT所取代。然而，到目前为止，PZT器件的应用一直受到成本和性能的限制。特别是，虽然广泛用于从笔记本电脑变压器到执行器的中高电压，但这种技术在低电压应用中遇到了困难，使其无法应用于电子电源和适配器等关键应用。其目的是模仿MLCC技术，使其具有两个基本区别：更复杂的材料，最终多层器件的极化，以及使这种多层电极陶瓷生产能够消除制造资本设备的繁重成本。该项目更广泛的影响/商业潜力将是，它将直接使PZT技术应用于广泛的极低/中压(低至高阻抗电气负载)电力电子应用，就像采用MLCC技术的电子产品所实现的那样。它将使包括电源、电压传感器、隔离器和负载点逆变器在内的非磁性电力电子产品能够显著减少电磁接口(EMI)和射频接口(RFI)问题，并为发光二极管(LED)照明和低成本太阳能等基于新兴电子产品的消费品带来更环保的技术解决方案。与基于磁性的产品相比，这项新技术可能更小、更轻，生产成本更低。目前，磁性产品是数量庞大的消费产品和应用的唯一选择，这些产品和应用包括所有移动电子产品、游戏机、无线通信，甚至包括车辆、航空航天和家庭使用的所有控制板。

This Small Business Innovation Research (SBIR) Phase I project will investigate development of a Lead Zirconium Titanate (PZT) analog of multilayer ceramic capacitor (MLCC) technology. Typically comprised of Barium Titanate materials, MLCC devices are the most produced and used capacitors in electronic industry with a produced quantity of approximately 1000 billion pieces per year. However, as a piezoelectric material, Barium Titanate has been largely replaced by PZT. However, PZT device applications have been constrained until now by both cost and performance. In particular, although used extensively for mid-high voltages that extend from laptop transformers to actuators, such technology struggles with low voltage applications prohibiting it from key applications such as electronics power supplies and adaptors. The aim is to emulate MLCC technology with two fundamental distinctions more complex materials poling of final multilayer devices and enabling such multilayer electroded ceramic production that eliminates the onerous cost of capital equipment to manufacture. The broader impact/commercial potential of this project will be that it directly enables application of PZT technology to a wide range of very low/mid voltage (low to high impedance electrical load) power electronics applications, much as has been accomplished for electronics with MLCC technology. It will enable non-magnetic power electronics including supplies, voltage sensors, isolators, and point-of-load inverters that both drastically reduce electromagnetic interface (EMI) and radio frequency interface (RFI) issues and lead to a far greener technology solution for emergent electronics based consumer goods, such as light-emitting diode (LED) lighting and low cost solar energy. The new technology is potentially smaller, lighter weight and less cost to produce than magnetics-based products, which, at present, is the only option for this enormous array of volume consumer products and applications that include all mobile electronics, gaming consoles, wireless communication, and indeed all control boards used in vehicular, aerospace and domestic use.
