Abstract: An adhesion element with variable surface adhesive force comprises a substrate, a heating layer, a buffer layer and a nanostructure array. The heating layer is formed on one side of the substrate, wherein a temperature of the heating layer is changeable by a power supply. The buffer layer is formed on the heating layer. The nanostructure array is formed on the buffer layer, and the nanostructure array is made of a metallic glass material and comprises a plurality of nanostructures which are spaced apart from one another and together form an ordered array. The plurality of gas chambers are formed by the nanostructure array.

Abstract: Disclosed is a medical needle used for performing a piercing or insertion operation on an object repetitively, the medical needle comprising a needle body and a metallic glass material layer formed on a surface of the needle body, the metallic glass material layer comprising an alloy consisting of aluminum, zirconium, copper and tantalum. With the presence of the metallic glass material layer covering the needle body, the medical needle may maintain its sharpness after having performed multiple piercing or insertion operations to enhance durability, minimize the increase of maximum piercing or insertion force resulted from piercing or insertion operations, and decrease injury to the object caused by piercing or insertion operations.
