SBIR Phase I: Cobond/Cofired Capacitor Based Electronics

这项小型企业创新研究（SBIR）一期项目将研究开发一种钛酸铅锆（PZT）模拟多层陶瓷电容器（MLCC）技术。MLCC器件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，年产量约为1万亿件。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，PZT器件的应用到目前为止一直受到成本和性能的限制。特别是，虽然广泛用于中高压，从笔记本变压器延伸到执行器，这种技术在低压应用中挣扎，禁止它在电子电源和适配器等关键应用中使用。其目的是模仿MLCC技术，有两个基本的区别：更复杂的材料，最终多层器件的极点，以及使这种多层电极陶瓷生产消除了沉重的资本设备制造成本。该项目的更广泛的影响/商业潜力将是它直接使PZT技术应用于各种极低/中压（低到高阻抗电负载）电力电子应用，就像使用MLCC技术完成的电子产品一样。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大幅减少电磁接口（EMI）和射频接口（RFI）问题，并为新兴电子消费品（如发光二极管（LED）照明和低成本太阳能）带来更加绿色的技术解决方案。这项新技术可能比基于磁性的产品更小，重量更轻，成本更低，目前，磁性产品是大量消费产品和应用的唯一选择，包括所有移动电子产品，游戏机，无线通信，以及车辆，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.
