 This paper reviews the various fabrication techniques used to create biomimetic micro-nano array surfaces. These surfaces can be created using top-down or bottom-up approaches such as etching, templating, self-assembly, and electrospinning slash electrospraying. The paper then discusses how these surfaces change when subjected to external forces, such as temperature, pressure, and electricity. It also examines the applications of these surfaces in areas like droplet transport, adhesion properties, sensors, and soft robotics. Finally, it identifies potential future research directions for further development of biomimetic micro-nano array surfaces. This article was authored by Chowli, Jun Jun Yang, Wen Jun He, and others.
