  • Patent number: 11785370
    Abstract: Proposed is a vibration sensor including: a substrate; a first electrode positioned on the substrate; a support positioned on the first electrode and including a cylindrical hollow hole; and a diaphragm including a thin film positioned on the support and a second electrode positioned on the thin film. According to the present disclosure, it is possible to manufacture a skin-attachable vibration sensor that is attached to a user's neck to detect vibration acceleration in user's neck skin, thus exhibiting a uniform and high sensitivity to a user's voice over the frequency range of the human voice. In addition, the sensor sensitively detects a user's voice through neck skin vibrations rather than through air, thus being free from the influence of external noise or wind, and can recognize the user's voice even in a situation where a user's mouth is covered.

  • Patent number: 10700437
    Abstract: A communication device for controlling a beam in a wireless communication system and a method therefor are provided. The communication device includes a lens including at least one layer in which unit cells are disposed, at least one processor configured to determine a beam pattern and control capacitance of each of the unit cells based on the beam pattern, and a transceiver for transmitting a signal in the determined beam pattern through the lens, which is capacitance-controlled. Each unit cell includes a first conductive member, a second conductive member overlapping at least a portion of the first conductive member, and spaced apart from the first conductive member, and a dielectric interposed between the overlapped portions of the first conductive member and the second conductive member. An overlap region of the first and second conductive members is arranged in a direction shielded from an external electromagnetic wave.

  • Publication number: 20180190762
    Abstract: Disclosed is a flexible substrate laminate including a flexible substrate and a base member configured to reduce strain of the flexible substrate on one surface of the flexible substrate. The flexible substrate laminate includes the base member for reducing surface strain to thus decrease the surface shear stress and surface strain thereof, thereby minimizing deterioration in the performance of a device. When the flexible substrate laminate is applied to various electronic devices, the electronic devices can exhibit improved bending resistance while the performance thereof is prevented from decreasing even after bending.

  • Patent number: 9718251
    Abstract: Disclosed herein is a laminate comprising: a substrate; an organic surface modifying layer disposed on the substrate; and a porous organic semiconductor layer disposed on the surface modifying layer. Onto the substrate, introduction of the organic surface modifying layer having a low surface energy, and optionally the organic intermediate layer having a low glass transition temperature controls the self assembly of the organic semiconductor layer, allowing the porous organic semiconductor layer to have high crystallinity and large crystal grains. Also, provided is a highly efficient chemical sensor comprising the laminate.
