Bionic sweat gland and bionic skin

A bionic sweat gland and bionic skin (7). The bionic sweat gland comprises a casing (1) and a porous medium (3). The casing (1) is internally provided with a heat dissipation tube. The heat dissipation tube is filled with the porous medium (3). Pores formed by the porous medium (3) in the heat dissipation tube gradually decrease along the evaporation flow direction. Gaps in the porous medium (3) are filled with an evaporation solution. The casing (1) is a water-permeable structure and is used to suction evaporation liquid from the environment. A plurality of through-holes communicating with the heat dissipation tube are provided at the top of the casing (1) and are used to discharge evaporation liquid to the outside. The acting effect of tensile shear force generated during use on the surface of a flexible material, such as electronic skin, can be adapted. Compared with a hardware-type heat exchange method that depends on a convective heat exchange method and a forced air cooling method for a single-phase fluid, a heat exchange method having a flexible feature has better adaptability and more application occasions.
