Fibrillar dry adhesives are widely used due to their effectiveness in air and vacuum
conditions. However, their performance depends on various factors. Previous studies have …

Dynamic adhesion characteristics of synthetic adhesives have attracted massive attention
recently. Specific to the mushroom-shaped adhesive structures with outperformed adhesion …

Friction control has attracted significant attention due to its potential to improve device
efficiency and reduce wear. However, achieving rapid, reversible, and robust friction …

The gradient modulus in beetle setae plays a critical role in allowing it to stand and walk on
natural surfaces. Mimicking beetle setae to create a modulus gradient in microscale …

Fibrillar dry adhesives have shown great potential in many applications thanks to their
tunable adhesion, notably for pick-and-place handling of fragile objects. However …

The contact splitting hypothesis (CSH) has been proposed for around 20 years, which
suggests that the patterned or fibrillar surfaces enable very efficient biological attachment …

Viscoelasticity is well known to cause significant hysteresis of crack closure and opening
when an elastomer is brought in and out of contact with a flat, rigid, adhesive counterface. A …

The adhesion of a rigid substrate and an adhered straight cylindrical punch with a non-
homogeneous elastic modulus is analyzed. The stress distributions are obtained along the …

Bioinspired fibrillar adhesives have been proposed for novel gripping systems with
enhanced scalability and resource efficiency. Here, we propose an in-situ optical monitoring …

Adhesive contacts which possess a dominant stress concentration, such as at the contact
edge in spherical junctions or at the detachment front in a peeling film, are well studied …
