Abstract: A sensor device is for detecting metal. The sensor device may have a substrate, an electrode on the substrate, and a biopolymer-metal composite film on the electrode. The biopolymer-metal composite film may include a metal and a biopolymer. The sensor device may further have circuitry coupled to the electrode and configured to apply a sensing signal to the electrode.

Abstract: A fluid mixing method using a micromixing apparatus which includes a mixing microchannel having a channel length and a continuously variable channel width defined by a first sidewall surface and an opposing second sidewall surface. The channel width varies from a minimum channel width h to a maximum channel width H in a ratio of H:h≧1.1:1.0. A first inlet injects a first fluid and a second inlet a second fluid into the mixing microchannel which both flow in a flow direction in the mixing microchannel along the channel length. The first sidewall surface includes first curved surface portions and the second sidewall surface includes second curved surface portions. The first and second curved surface portions are non-overlapping to provide the variable channel width. The flow velocity profile is passively varied and exclusively controlled by the continuously variable channel width.

Abstract translation: 一种使用微混合装置的流体混合方法，该混合装置包括具有通道长度和由第一侧壁表面和相对的第二侧壁表面限定的连续可变通道宽度的混合微通道。 通道宽度以H:H≥1.1:1.0的比例从最小通道宽度h到最大通道宽度H变化。 第一入口将第一流体和第二入口将第二流体注入混合微通道，所述混合微通道沿着通道长度在混合微通道中沿流动方向流动。 第一侧壁表面包括第一弯曲表面部分，第二侧壁表面包括第二弯曲表面部分。 第一和第二曲面部分不重叠以提供可变通道宽度。 流速分布被动地变化，并且由连续可变的通道宽度专门控制。
