SBIR Phase I: Cobond/Cofired Capacitor Based Electronics

这个小型企业创新研究（SBIR）第一阶段项目将研究开发多层陶瓷电容器（MLCC）技术的锆钛酸铅（PZT）类似物。 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，每年生产量约为10000亿件。然而，作为压电材料，钛酸钡已在很大程度上被PZT取代。 然而，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延伸到致动器的中高压，但这种技术在低压应用中苦苦挣扎，使其无法用于电子电源和适配器等关键应用。 其目的是模仿MLCC技术的两个基本区别，更复杂的材料极化的最终多层器件，并使这种多层电极陶瓷生产，消除了资本设备制造的沉重成本。 该项目更广泛的影响/商业潜力将是，它直接使PZT技术应用于广泛的极低/中压（低到高阻抗电气负载）电力电子应用，就像MLCC技术的电子产品一样。 它将使非磁性电力电子产品，包括电源，电压传感器，隔离器和负载点逆变器，大大减少电磁接口（EMI）和射频接口（RFI）问题，并为基于新兴电子产品的消费品（如发光二极管（LED）照明和低成本太阳能）带来更环保的技术解决方案。 与基于磁性的产品相比，新技术可能更小、重量更轻、生产成本更低，而基于磁性的产品目前是大量消费产品和应用的唯一选择，包括所有移动的电子产品、游戏机、无线通信以及实际上用于车辆、航空航天和家用的所有控制板。

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.
