The first adhesive layer is used for contacting with an object to be detected and adsorbing on the object to be detected, such as human skin. In a specific embodiment, a material with adhesive property, such as glue or adhesive tape, can be disposed on one side of the first adhesive layer substrate 111. In another possible embodiment, the first adhesive layer substrate 111 may be itself absorbent or may be provided with an absorbent structure.
