Abstract
Disclosed are a negative pressure driven sucking apparatus and a preparation method thereof. The sucking apparatus comprises a sucking disc body, wherein a negative pressure cavity is formed in the middle of the sucking disc body, and the negative pressure cavity is connected with a vacuum line, and the bottom of the negative pressure cavity having a flexible section, and an annular wedge-shaped microstructure is formed at the bottom of the body surrounding the flexible section. Stable loading and release processes of the annular wedge-shaped microstructure are realized.
