    摘要： Embodiments described herein may be useful in the detection of analytes. The systems and methods may allow for a relatively simple and rapid way for detecting analytes such as chemical and/or biological analytes and may be useful in numerous applications including sensing, food manufacturing, medical diagnostics, performance materials, dynamic lenses, water monitoring, environmental monitoring, detection of proteins, detection of DNA, among other applications. For example, the systems and methods described herein may be used for determining the presence of a contaminant such as bacteria (e.g., detecting pathogenic bacteria in food and water samples which helps to prevent widespread infection, illness, and even death). Advantageously, the systems and methods described herein may not have the drawbacks in current detection technologies including, for example, relatively high costs, long enrichment steps and analysis times, and/or the need for extensive user training. Another advantageous feature provided by the systems and methods described herein includes fabrication in a relatively large scale. In some embodiments, the systems and methods may be used in conjunction with a detector including handheld detectors incorporated with, for example, smartphones (e.g., for the on-site detection of analytes such as pathogenic bacteria).

    摘要： Electromechanical devices described herein may employ tunneling phenomena to function as low-voltage switches. Opposing electrodes may be separated by an elastically deformable layer which, in some cases, may be made up of a non-electrically conductive material. In some embodiments, the elastically deformable layer is substantially free of electrically conductive material. When a sufficient actuation voltage and/or force is applied, the electrodes are brought toward one another and, accordingly, the elastically deformable layer is compressed. Though, the elastically deformable layer prevents the electrodes from making direct contact with one another. Rather, when the electrodes are close enough to one another, a tunneling current arises therebetween. The elastically deformable layer may exhibit spring-like behavior such that, upon release of the actuation voltage and/or force, the separation distance between electrodes is restored. Thus, the electromechanical device may be actuated between open and closed switch positions.
