论文摘要
The leeches can stably adhered to the surface of the host or a variety of natural rough surfaces, but up to now, people have little understanding of the adhesion mechanism of the leeches and its influencing factors. In order to understand the adhesion mechanism of leeches and its influencing factors, the microstructure and morphology of the anterior and posterior suckers of Whitmania pigra were observed. At the same time, the adhesion process of the posterior suckers and the autonomous and passive detachment process were recorded with a video camera. In addition, we tested the adhesive force of leeches on different roughness, different material surfaces and different temperature conditions, and carried out a comparative tensile test of leech exudate and distilled water. According to the results of the test characterization, we have obtained the following conclusions: the adhesive force of leeches is mainly due to the vacuum effect, while the secretion of sucker is mainly used for sealing, and the temperature, surface roughness and adhesion materials all have a certain influence on the adhesion of leeches. This study can provide insights for the bionic design of suction cup with high adsorption performance.
