The gecko model is a biologically inspired design concept inspired by the special abilities of this small reptile. Geckos are known for their unique foot structure and strong attachment ability, which allows them to freely climb, hang, and even hang upside down on a variety of surfaces. By deeply studying the biological mechanisms of geckos, scientists have gradually developed a new type of robot and material design concept, namely the gecko model.

The key to a gecko's foot is its microstructure. The soles of geckos' feet have thousands of tiny hairs (called "setae") that can interact with surfaces at a molecular level to form van der Waals forces. This weak but strong adsorption force allows geckos to walk freely on smooth and vertical surfaces. Based on this principle, researchers are exploring the use of gecko models to design new types of materials and robots, especially in the fields of medicine, architecture, and space exploration.

In the medical field, the application of gecko models can improve the effectiveness of wound healing and regenerative medicine. For example, a tape designed to mimic the structure of a gecko's foot can be attached to an open wound without causing secondary damage to the skin. This approach not only improves treatment effectiveness, but also significantly reduces the risk of infection.

In the field of architecture, the inspiration of the gecko model has also promoted the development of self-cleaning surfaces. These surfaces effectively reduce the adhesion of dust and dirt, thereby reducing cleaning costs and extending the service life of the building. At the same time, based on the mechanisms of the gecko model, scientists are also working on new types of climbing robots that are capable of performing various tasks in complex environments, such as search and rescue, inspection and maintenance.
