SmartSys, Volume 2, Issue 1, March 2026.ABSTRACT The rapid expansion of Internet of things (IoT) and cyber‐physical systems presents a formidable challenge for sustainably powering massive numbers of distributed sensors. Friction, a ubiquitous phenomenon typically viewed as a source of energy dissipation, offers a novel avenue for energy harvesting and in situ sensing.

Contact of a spherical probe with a stretched rubber substrate
, 2017 We report on a theoretical and experimental investigation of the normal contact of stretched neo-Hookean substrates with rigid spherical probes. Starting from a published formulation of surface Green's function for incremental displacements on a pre ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract Tectonic faults can slip in a spectrum of fault slip behaviors, from aseismic slip and slow ruptures to elasto‐dynamic earthquakes. Following frictional theory, laboratory experiments have shown that the basic ingredient that may control this transition is the interaction between the fault stiffness and the surrounding elastic medium.

International Wound Journal, Volume 23, Issue 3, March 2026.ABSTRACT This study evaluated the frictional properties of the skin‐contact interfaces of two multilayer prophylactic dressings under simulated perspiration conditions. The tested dressings were identical except for the skin‐contact interface, which was either silicone‐made or Hydrofiber‐made, that is, AQUACEL Hydrofiber Technology.

The Promise of Solid Lubricants for a Sustainable Future
Advanced Materials, Volume 38, Issue 8, 6 February 2026.Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?

The role of adhesion in contact mechanics
, 2018 Adhesive [e.g. van der Waals] forces were not generally taken into account in contact mechanics until 1971, when Johnson, Kendall and Roberts (JKR) generalized Hertz' solution for an elastic sphere using an energetic argument which we now recognize to be

Controlling turbulent drag across electrolytes using electric fields
, 2017 Reversible in operando control of friction is an unsolved challenge crucial to industrial tribology. Recent studies show that at low sliding velocities, this control can be achieved by applying an electric field across electrolyte lubricants.

Electrically Tunable Friction: From Sticky to Slippery with Ionic Hydrogels
Advanced Materials, Volume 38, Issue 8, 6 February 2026.This work demonstrates electrically tunable friction “from sticky to slippery” using ionic hydrogels, achieving reversible more‐than‐fifty‐fold modulation without liquid lubricants. An electric field extracts a salt‐rich interfacial layer that dramatically reduces friction.

Tribology theory versus experiment [PDF]
Tribology, the study of friction and wear of materials, has achieved a new interest because of the need for energy conservation. Fundamental understanding of this field is very complex and requires a knowledge of solid-state physics, material science ...

Static and Dry Friction due to Multiscale Surface Roughness
, 2008 It is shown on the basis of scaling arguments that a disordered interface between two elastic solids will quite generally exhibit static and "dry friction" (i.e., kinetic friction which does not vanish as the sliding velocity approaches zero), because of
