    • A first insulated planar metallic surface is formed under a surface of a substrate which is orientated a first way to an edge of the substrate. A Faraday shield is formed when a second insulated planar metallic surface is juxtaposed to and segregates the first insulated planar metallic surface from the remained of the substrate. The first way can be parallel or perpendicular forming either an edge or surface Coulomb island, respectively. Both planar surfaces can be charged either by mechanical contact or induced charging, Fowler-Nordheim and ion implantation. A Coulomb force is generated between two charged Coulomb islands each located on a different substrate. In addition, these Coulomb islands can also be used as capacitors to transfer signals between the substrates. The Faraday shield can be used to increase the Coulomb force while the potential applied to the shield can alter the Coulomb force.
    • 第一绝缘平面金属表面形成在基板的表面上,该基板的第一路定向到基板的边缘。 当第二绝缘平面金属表面并置并将第一绝缘平面金属表面与基板的剩余部分分离时,形成法拉第屏蔽。 第一种方法可以分别平行或垂直地形成边缘或表面库仑岛。 可以通过机械接触或诱导充电,Fowler-Nordheim和离子注入来对两个平面表面进行充电。 在两个电荷的库仑岛之间产生库仑力,每个库仑位于不同的基底上。 此外,这些库仑岛也可以用作电容器以在衬底之间传输信号。 法拉第盾可用于增加库仑力,而施加到盾牌的电位可以改变库仑力。

    • A LoC (Lab on a Chip) is described to analyze surface properties of fluid drops. Substrates with cavities near the edge are filled with fluids that have a contact angle greater than 90°. The surfaces of two different drops can be brought in contact with one another by using Coulomb forces. Several experiments can be carried out while the drops are in contact: the concentration of the fluid in each drop can be altered, tangential and normal forces can be applied to the contact surface, voltage differences across and current flow through the contact surface can be monitored. MEMS pumps can be used to mix reagents or buffers with the fluid to determine the protein concentration or to extract DNA from whole cells, respectively. Substrates holding optical components can be used to align fibers with either lasers or receivers. The alignment is automatic and controlled by a control unit.
    • 描述了LoC(芯片实验室)来分析液滴的表面性质。 具有靠近边缘的空腔的衬底填充有接触角大于90°的流体。 两个不同液滴的表面可以通过使用库仑力相互接触。 可以在液滴接触时进行几个实验:可以改变每个液滴中的流体浓度,可以将切向和法向力施加到接触表面,可监测通过接触表面的电流差异和流过接触表面的电流。 。 可以使用MEMS泵将试剂或缓冲液与流体混合以确定蛋白质浓度或分别从全细胞中提取DNA。 保持光学部件的基板可用于将光纤与激光器或接收器对准。 对位是自动的,由控制单元控制。
