  • Patent number: 11300470
    Abstract: The present invention discloses a flexible temperature-sensitive pressure sensor based on nanoparticle array quantum conductance, and an assembly method and application thereof. The sensor includes a high polymer film, metal nanoparticle arrays, metal microelectrodes, and an external circuit for conductance measurement; at least one group of metal nanoparticle arrays are deposited on upper and lower surfaces of the high polymer film, and in the same group, positions of metal nanoparticle arrays on the upper and lower surfaces are in one-to-one correspondence; the metal microelectrodes are arranged on two sides of each group of metal nanoparticle arrays and are symmetrically distributed on the upper and lower surfaces of the high polymer film; and the external circuit for conductance measurement is electrically connected to the metal microelectrodes. Conductance response signals of the nanoparticle arrays in the present invention have an exponential relationship with a distance between particles.

  • Patent number: 8330464
    Abstract: Disclosed herein is a three dimensional small bin electromagnetic consecutive array data acquisition method used in oil exploration comprising the steps of recording data using small bin lattices on execution of arrangement electrodes, each acquisition station (Ex, Ey) records the natural electromagnetic field time series data with the same acquisition parameter simultaneously; interference is removed first, for recorded data processing to get interference-free data; for border points and center point, the recording point serves as center point, and the same component from adjacent two points to total points area added together to obtain the average value of electric field data at time domain for each observation point; for corner points, the average values of the same electric field component from adjacent two points to total survey points toward bin direction is calculated; the electric field components acquired in maximum space serve as the new electric field values respectively; new time series data acqui
