  • Publication number: 20250130149
    Abstract: Provided is a driving device for detecting mechanical characteristics and electrical characteristics of cells. A structure of the driving device includes a piezoelectric stack, a bridge-type flexible hinge mechanism, a parallel hinge mechanism, a lead screw guide rail, a stepping motor, a linear displacement sensor, a force sensor, a ceramic needle, a first electrode, a second electrode, a cell container, an XY axis displacement platform, a positioning hole, a first metal base, a second metal base, a first metal connecting plate, a second metal connecting plate, a first pre-tightening wedge, a second pre-tightening wedge, screws, and a pre-tightening screw. During the operation of the driving device, the piezoelectric stack is driven under an excitation effect of a driving electric field signal, such that the bridge-type flexible hinge mechanism stretches, and the ceramic needle is driven by the parallel flexible hinge mechanism to move downwards.

  • Patent number: 12183997
    Abstract: The present disclosure belongs to the field of radio frequency circuit design, and in particular relates to a M×N millimeter wave and terahertz planar dipole end-fire array antenna. The M×N millimeter wave and terahertz planar dipole end-fire array antenna is composed of M paths of N× end-fire linear array antennas arranged at equal intervals, and the distance d between two adjacent N× end-fire linear array antennas is less than ?, where ? is the wavelength, and both M and N are integers greater than 1. By connecting linear type feed networks of the M paths of N× end-fire linear array antennas to M-path in-phase radio frequency signal transmitter and controlling the distance between two adjacent N× end-fire linear array antennas to be less than the effective wavelength, a higher gain and a higher half-power width can be realized, and the power consumption of the transmitter can be reduced.
