This invention relates to the design and fabrication method of a stretchable and shapeable thermoelectric device based on high-performance thin-film materials. First, a regular "paper-cut structure" array pattern is cut into a substrate thin-film material. Then, high-performance p-type and n-type thermoelectric materials are deposited sequentially on the substrate. Finally, electrode materials are deposited to connect the p-type and n-type thermoelectric materials in series. The thin-film thermoelectric device based on the paper-cut structure of this invention can transform from a two-dimensional planar structure to a three-dimensional structure under external force, changing the heat conduction within the device from a planar direction to a vertical direction, maximizing the utilization of the temperature difference between the heat source and the environment, and improving the device's power generation performance. Due to the three-dimensional network structure of the device itself, the cold end of the device can effectively exchange heat with the environment without the need for an additional heat dissipation module. The device structure of this invention is ingeniously designed, with strong compatibility in the fabrication process, and has significant application prospects in the field of wearable self-powered devices.

This invention discloses a gas storage tank and its preparation method. The gas storage tank includes a tank body and a damping coating. The damping coating is attached to the inner wall of the tank body. The damping coating includes a semi-dry first damping coating layer, a second damping coating layer, and fiberglass cloth. The fiberglass cloth is embedded between the first and second damping coating layers and fused and cured to form the final shape. The beneficial effects of this invention are: it abandons traditional passive noise reduction methods such as external sound insulation cotton and silencers, which have strong penetration and slow attenuation of low-frequency noise and have limited effectiveness. By forming a double-layer coupled structure of a metal substrate and a composite damping layer within the metal wall of the gas storage tank, firstly, when the gas storage tank is subjected to forced vibration, the bending deformation of the metal wall of the gas storage tank will cause the damping coating on the surface to undergo shear deformation synchronously; secondly, the polymer chains and filler particles inside the damping coating will generate internal friction due to relative displacement, converting the mechanical energy of the vibration into heat energy for dissipation, thereby weakening the vibration amplitude and reducing the resonance amplitude from the source.
