Title
Effect of tribological factors on wet adhesion of a microstructured surface to peritoneal tissue
Abstract

Bio-inspired microstructured surfaces have been developed that attach effectively to a wet surface. However, little is known about the associated tribological and adhesion properties involved. In this paper, the adhesion of a microstructured surface to peritoneal tissue is investigated as a function of preload, speeds of approach and angle of tilt to the horizontal. Results show that within a critical range of preload and speed of approach of the microstructured surface to the tissue result in good adhesion characteristics at the micro-structured surface/tissue interface. The microstructured surface adhesion to the tissue and the payload supported against gravity depend significantly on the tilt angle to the horizontal. Furthermore, a wet adhesion model was used to elucidate the adhesion mechanism of the microstructured surface to a wetted glass. These tests provide significant initial data for the design of a miniature mobile intra-abdominal device which drives the need for this adhesion study.
