    摘要： A method and system of measuring the spectroscopic impedance of a sensor and its immediate surroundings. The sensor is disposed on an engineered structure and is coated with a protective coating. The method includes providing a first optical signal having a first modulation frequency and amplitude. The method also includes transmitting the first optical signal and a second optical signal from a first location to a sensor location. The method also includes modulating the second optical signal with a second modulation frequency and amplitude, the second modulation frequency and amplitude converted from the first optical signal. The method also includes comparing the first modulation frequency to the second modulation frequency to determine one of a phase difference and a time lag and calculating the electrochemical impedance spectroscopy of the sensor and its immediate surroundings as a function of frequency.

    摘要： A filter includes a carbon nanotube film. The carbon nanotube film includes a plurality of linear carbon nanotubes, the linear carbon nanotubes being entangled with each other to form a number of micropores, wherein the diameters of the micropores are less than 10 nanometers. The method for making the filter includes the following steps: (a) providing a carbon nanotube array formed on a substrate; (b) removing the carbon nanotube array from the substrate to obtain a raw material of carbon nanotubes; (c) adding the raw material of carbon nanotubes into a solvent to obtain a flocculent structure; and (d) separating the flocculent structure from the solvent and shaping the flocculent structure to obtain a filter.
