摘要： One aspect of the invention relates to an ultrathin micro-electromechanical chemical sensing device which uses swelling or straining of a reactive organic material for sensing. In certain embodiments, the device comprises a contact on-off switch chemical sensor. For example, the device can comprises a small gap separating two electrodes, wherein the gap can be closed as a result of the swelling or stressing of an organic polymer coating on one or both sides of the gap. In certain embodiments, the swelling or stressing is due to the organic polymer reacting with a target analyte.

摘要： A chemical sensor that works while being submerged in a highly conductive medium is described. The chemical sensor includes hydrophobic structures that are distributed on conductive electrodes and are separated by small air cavities while submerged in the conductive medium. The hydrophobic structures are arranged such that their hydrophobicity varies in response to exposure to a target analyte. The change in the level of hydrophobicity results in permeation of the conductive liquid on to the conductive electrodes, thereby reducing the resistance levels between the conductive electrodes. The sensor indicates presence of the target analyte in response to detection of a change in resistance between at least two of the conductive electrodes.

摘要： A volume holographic imaging system enables the projection of a two-dimensional (2D) slice of a four-dimensional (4D) object. The 4D source object is illuminated to emit or scatter an optical field. A holographic element having one or more recorded holograms receives and diffracts the optical field into a diffracted plane beam. A phase mask is encoded in one or more multiplexed holographic gratings of the holographic element using a spatial filter. A collector lens focuses the diffracted plane beam to a 2D slice of the 4D probing source object. The focused 2D slice is projected onto a 2D imaging plane. The holographic element may have multiple multiplexed holograms that are arranged to diffract light from a corresponding slice of the 4D probing source object to a non-overlapping region of the detector.

摘要： A switching system is disclosed for an optical signal. The switching system includes a first optical waveguide coupled to a first electrode, a second electrode, and a second optical waveguide. The second optical waveguide is coupled to a movable electrode. The movable electrode is supported by a support structure and is positioned with respect to the first and second electrodes so that the position of the movable electrode may be selectively placed in either a first closed state or a second open state defined by the first and second electrodes under application of a voltage with respect to one of the first and second electrodes. The first closed state provides that the first and second optical waveguides are sufficiently close to each other to provide optical coupling therebetween while the second open state provides that the first and second optical communication channels are not sufficiently close to each other to provide optical coupling therebetween, or provide some different amount of optical coupling than in the first closed state.

摘要： The electro-mechanical micro-switch device includes first and second fixed electrodes. A movable electrode is positioned with respect to the first and second fixed electrodes so that the position of the movable electrode can be selectively placed in one of two opposing states defined by the fixed electrodes. The stored elastic potential energy of the movable electrode and its flexible supporting structure is used for switching between the two states. An electrostatic hold voltage is used to hold the movable electrode in the two switch states.
