This Small Grant for Exploratory Research (SGER) project will explore design concepts and manufacturing strategies for the NanoGate considering mechanics, tribology, and actuation, and will build prototype NanoGates used to act as relays and as fluid valves. The attempt is to create a new micro mechanical element that will have application in devices from fluid valves to electric power relays. The fundamental premise of the NanoGate is that a contilevered beam with a force applied to its tip and bent against an anvil located between the tip and the base can create a desired shape in the beam, independent of the beam thickness. This enables the beam to act as a transmission: when the tip is deflected 10 microns between the anvil and the base, the beam may deflect 10 angstroms. Similarly, a gap (open) or high force (closed) can be created between the beam and the anvil. Applications of this principle in fluid systems would enable researchers to create nanometer gaps and study the behavior of fluids at fundamental new scales. The research should enable complete indentification of the issues associated with this new device. There may be many system applications for the NanoGate element. For example, the NanoGate could be used to size nano particles. As a fluid valve, the NanoGate could use the polished top surface of a resilient plate to open and close off chambers to gate flow.

这项小额探索性研究资助 (SGER) 项目将考虑力学、摩擦学和驱动，探索 NanoGate 的设计概念和制造策略，并将构建用作继电器和流体阀的 NanoGate 原型。 尝试创建一种新的微机械元件，该元件将应用于从流体阀到电力继电器的设备中。 NanoGate 的基本前提是，对尖端施加力并靠着位于尖端和底座之间的砧座弯曲的倾斜梁可以在梁中产生所需的形状，而与梁的厚度无关。 这使得光束能够充当传输装置：当尖端在砧座和底座之间偏转 10 微米时，光束可能会偏转 10 埃。 类似地，可以在梁和砧座之间产生间隙（打开）或高力（闭合）。 这一原理在流体系统中的应用将使研究人员能够创造纳米间隙并在基本的新尺度上研究流体的行为。 该研究应该能够完全识别与该新设备相关的问题。 NanoGate元件可能有很多系统应用。 例如，NanoGate 可用于确定纳米颗粒的尺寸。 作为流体阀，NanoGate 可以使用弹性板的抛光顶面来打开和关闭腔室以控制流量。
