Leaf low adhesion mechanisms are complex and the interplay between the influencing parameters is not well understood. In this paper new approaches have been utilised to assess the role of leaf layer moisture versus humidity on low adhesion. Using controlled testing in a climate chamber as well as laboratory and field testing, leaf layer moisture relationships were explored. Moisture was found to be the most important characteristic when compared with environmental changes (such as humidity) and the relationship between moisture and traction is qualified.
