  • Patent number: 10762807
    Abstract: The invention discloses a circumferential laser dynamic display device, including an inner frame, having an inner frame pattern with multiframe microstructures made on surface; a sheet metal part, at least provided with first and second through holes, wherein the inner frame pattern is directly irradiated by a first beam of laser through the first through hole and by a second beam of laser through the second through hole; and a rotating shaft, with one end fixedly connected with a driving shaft, and the other end rotatably connected with the inner frame pattern. The rotating shaft can drive the inner frame pattern to do translational movement when rotating; wherein the translational movement of the inner frame enables the inner frame pattern to do circumferential movement relative to laser. The dynamic display device disclosed by the invention has simple structure, reasonable design and low production cost, and achieves circumferential dynamic image display.

  • Patent number: 10302586
    Abstract: A class of devices enabled by ionic conductors is highly stretchable, fully transparent to light of all colors, biocompatible or biodegradable, and capable of operation at frequencies beyond 10 kilohertz and voltages above 10 kilovolts. These devices enabled by ionic conductors can be used as large strain actuators, full-range loudspeakers, as strain or pressure sensors and as stretchable interconnects. The electromechanical transduction is achieved without electrochemical reaction. When large stretchability and high optical transmittance are required, the ionic conductors have lower sheet resistance than all existing electronic conductors.

  • Publication number: 20180244858
    Abstract: Hydrogel compositions, and corresponding methods of making, are provided. The hydrogels do not freeze, or only partially freeze, over a wide range of temperatures below the freezing temperature of water. Concurrently, these hydrogels also retain their room temperature mechanical properties (e.g., strength, modulus, elasticity) over a wide range of temperatures, including temperatures below the freezing temperature of water. The hydrogels are synthesized by adding a suitable amount of a salt together with previously cross-linked polymer gel. Hydration of the gel with aqueous solutions containing the prescribed salts not only depresses the hydrogel freezing point but protects the structure. For example, the salts do not allow the hydrogel to completely freeze, thus protecting the hydrogel from brittle failure. Whether the hydrogels partially freeze or remain non-frozen when chilled below the freezing temperature of water is determined by concentration of salt within the hydrogel.

  • Publication number: 20120035531
    Abstract: The invention provides a method to release drugs from a polymer matrix upon demand without degrading the matrix. By applying ultrasound to a self-healable polymer matrix in physiological environment, compounds of both low-molecular and high-molecular weights encapsulated in the matrix are delivered at controlled rates, while the integrity and stiffness of the matrix are unaffected.

  • Patent number: 7491892
    Abstract: The present invention relates to stretchable interconnects which can be made in various geometric configurations, depending on the intended application. The stretchable interconnects can be formed of an electrically conducting film or an elastomer material to provide elastic properties in which the interconnects can be reversibly stretched in order to stretch and relax the elastomer material to its original configuration. Alternatively, stretchable interconnects can be formed of an electrically conducting film or a plastic material to provide stretching of the material to a stretched position and retaining the stretched configuration. The stretchable interconnect can be formed of a flat 2-dimensional conductive film covering an elastomeric or plastic substrate. When this structure is stretched in one or two dimensions, it retains electrical conduction in both dimensions.
