  • Patent number: 11977207
    Abstract: Fully artificial, adaptive composite materials and systems, having variable transmittance, reflectance, and/or absorptance to radiation in visible, infrared, or other desired region of the electromagnetic spectrum, and methods of the manufacture and use thereof are provided. The adaptive composite materials and systems possess an unprecedented combination of properties and are, therefore, poised to enable a broad range of practical applications. The adaptive composite material incorporates at least one size-variable active area having a variable transmittance, reflectance, and/or absorptance in at least a portion of the electromagnetic spectrum and comprises at least: an elastomer substrate, a texturizing layer disposed on top of the substrate, and an optional reflective coating disposed on top of the texturizing layer. In operation, the stretching and relaxation of the elastomer substrate causes changes in the surface morphology of the texturized layers (e.g.

  • Patent number: 11650113
    Abstract: A torque-sensor strain beam structure and a torque sensor are provided. The torque-sensor strain beam structure comprises an external ring, a connecting hub and at least two strain beams. The external ring has a first joint. The connecting hub is located in the external ring and arranged coaxially with the external ring. The connecting hub has a second joint. A first end of each of the at least two strain beams is fixedly connected to an inner wall of the external ring and a second end of each of the at least two strain beams is fixedly connected to the connecting hub. A strain grid is provided on each of the at least two strain beams. A load inputting point is located at the first joint or the second joint. Arrangement of the torque-sensor strain beam structure allows the torque sensor to have smaller volume while having higher measurement sensitivity.
