Contact self-cleaning of synthetic gecko hair to enhance performance and reusability.
To study and model the process, mechanisms and mechanics of particle removal from synthetic adhesive microfibers.
Approach: Using a custom built two-axis adhesion and friction measurement system, we are able to study the process of cleaning a contaminated microfiber adhesive sample. Various mechanics of contact based self-cleaning such as sliding and rolling are considered in detail. We study the effect of loading conditions, particle-to-microfiber size ratio, material properties and microfiber structure on cleaning, and cleaning mechanisms.
Benefits: A thorough understanding of contact self-cleaning in adhesive microfibers will enhance the development of synthetic dry adhesives with robust performance is various environments.
