Abstract:
A method of forming an adhesive force includes removing a seta from a living specimen, attaching the seta to a substrate, and applying the seta to a surface so as to establish an adhesive force between the substrate and the surface. The seta is applied to the surface with a force perpendicular to the surface. The seta is then pulled with a force parallel to the surface so as to preload the adhesive force of the seta.
Abstract:
Embodiments of the present invention include hierarchically-dimensioned, microfiber-based dry adhesive materials featuring dense arrays of microfibers with free tips terminating in numerous microfibrils. In certain embodiments, more than two levels of microfiber-dimension hierarchy may be employed, each dimension involving smaller microfibrils emanating from the tips of the microfibers or microfibrils of the next highest dimensional level. Various additional embodiments of the present invention are directed to methods for preparing hierarchically-dimensioned, microfiber-based dry adhesive materials. These methods include single-pass or multi-pass imprint-lithography, pattern masking and etching, and imprinting fiber-embedded substrates followed by etching.

Abstract:
A fabricated microstructure includes a plurality of protrusions. The protrusions are capable of providing substantially parallel adhesive force at a surface of between about 60 and 2000 nano-Newtons. A flexible shaft supports the protrusions, and a flexible member or beam is attached to the shaft to form a manipulator or gripper device.
Abstract:
The invention provides unique releasable adhesive devices that are high-load bearing and highly stable while allowing adjustment of the weight-bearing angle in a wide range, thereby greatly expanding the scope of applications for technology. Adhesive systems and devices of the invention can be designed to fit applications ranging from household weight-bearing shelves and holders, components for transportation, athletic equipment, labels and advertising posts, automobile interior trims, permanent or reversible fasteners, as well as instruments and devices for industrial, commercial, medical or military applications.
Abstract:
Ein Haftverschlussteil (10) umfassend ein Trägerteil (12) und darauf aufstehend angeordnete Verschlussteile (14a - 14b), wobei jedes Verschlussteil (14a - 14b) zumindest ein eine vorgebbare Längenerstreckung (Hs) aufweisendes Stielteil (20a - 20b) aufweist, ist dadurch gekennzeichnet, dass an zumindest einem Stielteil (20a - 20b) in zumindest einem Längenabschnitt (24a - 24b) zumindest ein Formgebungsabschnitt (26a - 26b) vorgesehen ist, der gegenüber einer fiktiven Stielteilaußenform zumindest teilweise in Richtung zum Stielinneren zurückgesetzt ist, und dass der zumindest eine Formgebungsabschnitt (26a - 26b) eine elastische Verform- und/oder Bewegbarkeit längs und/oder quer zur Längenerstreckung (Hs) des jeweiligen Stielteils (20a - 20b) zumindest für dieses Stielteil ermöglicht.
Abstract:
The invention relates to a combination of a first device and a second device, wherein both devices comprise at least one surface and the surface of the first device comprises at least one recess. At least one contact surface is formed when the surface of the first device attaches to the surface of the second device. By applying external pressure, the adhesion force between the two devices can be switched back and forth between at least two states.
Abstract:
The invention relates to a moulded product comprising a substrate (1), to which a plurality of first fibres (10) is applied, the underside (11) of each fibre being permanently fixed to the surface (2) of the substrate (1), and a plurality of second fibres (20), the respective undersides (21) of which are permanently connected to the surfaces (12) of the first fibres (10). The flanks (15) of the first fibres (10) and the flanks (25) of the second fibres (20) are concave. The invention further relates to a method for producing a moulded product of this type and to the use of said product as the attachment surface of an object.
