Testing assembly for directional Gecko inspired adhesives

Abstract

Adhesius inspirats en geckos mostren utilitat en situacions on estats d'encès i apagat d'adhesió són necessaris. Aquests adhesius estan formats per microestructures elastomèriques (d'unes quantes micres de longitud) capaces d'adaptar-se a un substrat, i d'aquesta manera, poder adherir-se a un gran rang de materials. Aquest projecte desenvolupa un sistema d'experimentació capaç de caracteritzar la capacitat d'adhesió d'aquest tipus d'adhesius basats en geckos. El sistema és capaç de mesurar esforços normals i de cisallament, i l'àrea de contacte entre substrat i adhesiu. Una interfície gràfica permet a usuaris utilitzar el sistema sense entrenament excessiu. Alineament entre el substrat i adhesiu és possible gràcies a un sistema òptic capaç de detectar l'àrea que primer entra en contacte amb el substrat. Resultats consistents i reproduïbles s'obtenen per tal de poder comparar de forma objectiva diferents tecnologies d'adhesius i de neteja d'aquests.

Adhesivos inspirados en geckos muestran utilidad en situaciones donde estados de encendido y apagado de adhesión son necesarios. Estos adhesivos están formados por microestructuras elastoméricas (de unas cuantas micras de longitud) capaces de adaptarse a una superficie, y de esta forma, adherirse a un gran rango de materiales. Este proyecto realiza un sistema de experimentación capaz de caracterizar la fuerza de estos adhesivos. El sistema es capaz de medir esfuerzos normales, de tracción y el área de contacto entre adhesivo/sustrato. Una interfaz gráfica permite a usuarios, con poco entrenamiento con el sistema, utilizar el sistema. Alineamiento entre sustrato y adhesivo es posible gracias a un sistema óptico capaz de detectar el área de contacto entre estos. Resultados consistentes y repetibles se obtienen con el fin de poder comparar de forma objetiva diferentes tecnologías de fabricación y limpieza de estos.

Gecko inspired adhesives are useful for situations where on/off states of adhesion are needed. Such adhesives are made of microstructured elastomers (usually a few microns in length) that are able to conform to a substrate and thus, adhere to a wide range of materials. This project develops a testing assembly to characterize the strength of Gecko inspired directional adhesives. The system is able to measure the shear/normal forces and the contact area. An interface allows researchers to run tests without extensive training on the system. Alignment between pad/substrate is performed with the implementation of an optical system capable of the side of the pad that first touches the surface. Finally, consistent and reliable results are obtained to objectively compare different pad technologies as well as different pad cleaning methods.
