    摘要： A radiation detection technique employs field enhancing structures and electroluminescent materials to converts incident Terahertz (THz) radiation into visible light and/or infrared light. In this technique, the field-enhancing structures, such as split ring resonators or micro-slits, enhances the electric field of incoming THz light within a local area, where the electroluminescent material is applied. The enhanced electric field then induces the electroluminescent material to emit visible and/or infrared light via electroluminescent process. A detector such as avalanche photodiode can detect and measure the emitted light. This technique allows cost-effective detection of THz radiation at room temperatures.

    摘要： The disclosure is generally directed to fabrication steps, and operation principles for microelectromechanical (MEMS) transducers. In one embodiment, the disclosure relates to a texture morphing device. The texture morphing device includes: a plurality of supports arranged on a substrate to support a deformable mirror; an ITO layer; and a Distributed Bragg Reflector (DBR) layer. A pair of adjacent supports form a cavity with the ITO layer and the deformable mirror. When the height of the cavity changes responsive to an external pressure, the internal reflection within the cavity is changed. The change in the height of the cavity causes the exterior texture to morph. Similar principles are disclosed for constructing sensor and actuators.

    摘要： A method and apparatus for making analog and digital electronics which includes a composite including a squishable material doped with conductive particles. A microelectromechanical systems (MEMS) device has a channel made from the composite, where the channel forms a primary conduction path for the device. Upon applied voltage, capacitive actuators squeeze the composite, causing it to become conductive. The squishable device includes a control electrode, and a composite electrically and mechanically connected to two terminal electrodes. By applying a voltage to the control electrode relative to a first terminal electrode, an electric field is developed between the control electrode and the first terminal electrode. This electric field results in an attractive force between the control electrode and the first terminal electrode, which compresses the composite and enables electric control of the electron conduction from the first terminal electrode through the channel to the second terminal electrode.
