Abstract

Abstract: Many solutions for getting grip on varying substrates exist in nature and in technical applications, but they fail on substrate geometries they are not specifically designed for. A novel passive load‐dependent system is developed that creates high friction forces on a large variety of substrates: the granular media friction pad. With an elastic membrane encasing granular media, it reversibly undergoes the jamming transition only by varying the normal load. Here, the friction performance on different substrates is shown and the underlying physical mechanisms in a numerical simulation are investigated. Abstract : Many solutions for getting grip in nature and in technical applications fail on substrate geometries they are not specifically designed for. This paper presents the granular media friction pad (GMFP), a novel passive load‐dependent system creating high friction on diverse substrates. Using an elastic membrane encasing granular media, it reversibly undergoes the jamming transition only by varying the normal load.
